big.zip1k21-07-06File is not ratedProduct Digit Counter
Program can count the digits in the product of ANY two integers, no matter how large.
baseconversion.zip6k21-04-19File is not ratedBASECONV&BASECON2&3
These programs convert from any base 2-20, to any base 2-20. BASECONV is for integers and BASECON2 is for floating point numbers. i.e. You can convert a number like 125.875 in decimal to binary, and get 1111101.111. The programs are as simple as possible, with no safety catch built in. So if, for example, you choose from base two to base ten, and input a number like 1134, you will get, 22. There is also the limitation of the 14 significant digits in base 10: the number is first converted to a value memory in base10, so if it has more than 14 significant digits there, information is lost. BASECON3 gives the result as a fraction. If, for example, you input 156.48 in base 10, and convert it to base 16, you get: F48/19. The result is also shown in base 10: 3912/25.
chinrem84.zip1k21-04-11File is not ratedChinese remainder theorem
This program illustrates the Chinese remainder theorem. The user enters a list of moduli m and a list of remainders r. The program then shows an integer x with x = r[i] mod m[i] for all i.
approx.zip2k21-01-24File is not ratedApproximations
Five programs to give you approximations as fractions of rational and irrational numbers. One program, DFRAC, can also give a correct answer to 17/191+19/193+23/199 and similar fractions. The programs give one to six and more approximations depending of the number and program.
bignum.zip2k19-07-20File is not ratedBig Number Calculations
This program calculates big numbers which are accomplished with either exponentiation, multiplication, division, addition, or subtraction. For example: 789^5, 12345678901234567890/123, 147852369147852369-123456789012345, 12345678901234567890+ 12345678901234567890, 475896123617*963258741236. The operations are entirely list based, so you can get up to 999 digits. Should the result of a subtraction become negative, only the first digit in the resulting list is negative: For example, 191-888=-697, and the answer comes out as, {-6 9 7}. This is to be seen as: -600-90-7, NOT as, -600+90+7, i.e. all the digits are to be seen as negative, if the first one is so. The program also gives the sum of the digits in the resulting list. A bug in the division part has been corrected.
sqrtcalculator.zip2k17-11-18File is not ratedArbitrary Precision Square Root Calculator
This program will allow you to calculate the square root of an inputted number to as many decimal places as you prefer. This is more accurate than your calculator will normally give you! Also included is a program to calculate the golden ratio, phi, using the same algorithm.
frac.zip1k17-05-30File is not ratedFRAC and FRAC1
These programs can handle really large fractions, they are limited only by how many digits you can read, provided that there is an arithmetic expression. If you input a number like log(7), you get an approximation, the programs uses AFRAC1 for that.
arithmetics.zip6k17-02-10File is not ratedArithmetics
These six programs offer support for those tedious arithmetic homework tasks, wether you are suposed to add, subtract, multiply, and/or divide. If you are in primary school, they can save you a lot of time and effort. UPDATE: New in this version, ADDMORE, which lets you add up to six numbers. Also, ARITHMET, a menu-driven program containing the five individual programs
roots.zip1k17-01-13File is not ratedROOTS
ROOTS: This program calculates the roots for any index: 2, -3, 4…, 1/2, 1/3, -4/3…, when x and y in x√y are rational . So the program then relies on general formulas. Other than that, the built in formulas are used. So instead of just one root for every index, you get them all, plus their angles, provided x and y are rational. ROOTS1: If the above program is mostly for the math nerds, this program is a useful subroutine since it is short and also, like the other, does not miss out when the answer is an integer, which often happens with the built in x√y: 3√7^3, ( MATH 4 ) for example, gives an fPart = 1. Answers are the same as x√y. ROOTS2: This is a short and useful program, which does not miss out when the answer is an integer. Can handle imaginary/complex answers as well.
imagic.zip8k15-05-19File is not ratedIMAGIC
This is a very small ( 46 bytes ) program to help out with imaginary numbers like: i^-45, i^71, i^-3.5 and so on. Look at the screenshots.
dfrac.zip1k15-05-15File is not ratedDFRAC
This program is an improvement of CFRAC, a program which reduces rational numbers. It has capacity to handle fractions and expressions which requires a numerator and denominator of six digits. At the same time it is useful for separating rational numbers from irrational, as opposed to AFrac which has to high a precision. This program is essential when it comes to presenting fractions with the Output(-command, or when you are looking for the rational numbers amongst a set of numbers.
dfrac12.zip1k15-05-15File is not ratedDFRAC1&2
DFRAC1: This program is meant to help you with fractions in your schoolwork. It has a much bigger capacity than the built in program. You simply enter the expression, like for example: 1/4 - 8/17, and the program answers: -15/68, and after a while the expression comes up simplified: 17/68 - 32/68. An expression like 1/4 + 2/7*5/3 + 4/11, has the answer: 1007/924, and is simplified to: 231/924 + 440/924 + 336/924. DFRAC2: This program has the same function as DFRAC1, but the execution differs.
gcdlcm2.zip1k14-12-10File is not ratedGCD and LCM for Rational Numbers
GDCLCM: This program calculates the GCD and LCM for two rational numbers. So the program can even handle fractions, and i.e: Numbers that are smaller than one! It is necessary as a subroutine in a program that factors quadratic equations with rational coefficients, for example. I use it in QUADRA12. It doesn't matter in which order the numbers are entered, nor does it matter if they are positive or negative. GDCLCM1: This program calculates the GCD and LCM for several rational numbers. Just input the numbers as a list. Other than that it works the same way as the above program. GCDLCM2: This program is for integers only.
efrac.zip1k14-12-06File is not ratedEFRAC
This is an interesting application of Euklides’ algorithm: It is used to simplify expressions of fractions, whereas it’s usually used to find the greatest common divisor and/or the smallest common measurer. This little program has a much bigger capacity than the built in one, and is really fast. An expression like 17/191 + 19/193 comes out as, 6910 over 36863, in a fraction of a second.
lcm.zip1k14-11-28File is not ratedLeast Common Measurer
Two simple programs to determine the least common measurer, when there are more than two values involved. One works like when you do it on paper, and the other one shows the mathematics behind.
gcd1.zip1k14-11-28File is not ratedGreatest Common Divisor
Two simple programs to determine the greatest common divisor, when there are more than two values involved. One works like when you do it on paper, and the other one shows the mathematics behind.
kaprekar.zip3k14-11-19File is not ratedKaprekar's Constant
Take any 4-digit number that does not repeat the same digit, and sort its digits in ascending and descending order, to get two numbers. Then subtract the smaller number from the bigger and repeat the process with the number you then get, and you will find yourself with 6174 as a result, in less than 8 iterations! There are also at least five more constants, in bases other than 10, that follow from the same procedure.
morefactorials.zip1k14-11-14File is not ratedMore Factorials
This program will compute factorials for fractions with denominators 3 and 4 (the calculator already handles denominators of 2). It uses a recurrence relation rather than the Gamma function. Enjoy!
sumofsquares.zip5k14-10-13File is not ratedSum of Two Squares

This program will evaluate polynomials, but this program works if the coefficients or the input value is complex. The user inputs the coefficients of the polynomial in ascending powers order and then the value. The program returns the evaluation. Great for students being introduced to complex arithmetic. Enjoy!
between.zip2k13-04-01File is not ratedNumber in Between
The Property of Betweenness states that there is always another real number in between any two unique real numbers. This program finds a number in between after you input the unique numbers and a fraction.
primetest.zip1k13-02-11File is not ratedPrime-test
* Prime-test This program will test (darn quickly) how prime a number is, and display the first proof it finds if a number is composite. Try it- it's pretty quick. If you want real speed though, you'll write one in assembly.
simplify.zip3k13-01-02File is not ratedDecimal Simplifier
Decimal Simplifier is a program that simplifies decimals stored in the answer memory. For instance, sin(pi/4) = .7071067812 will simplify to the sqrt(2)/2. If you arrive at the decimal equivalents for any of the following, they will simplify: pi/3, -4e, 9*sqrt(5)/2, sqrt(6)-2i, pi*sqrt(511232), 5e*sqrt(439), pi+501/12, e+1/235, 80137/13812, -5/(2pi), 3pi^2, 5e^2, 7pi^2*sqrt(3), 8e^2*sqrt(2052338). These are just a few examples. Generally, Decimal Simplifier will act as a radical simplifier and simplify any fraction multiplied by 'pi' or 'e.'
zeller.zip1k12-10-15File is not ratedZeller's Congruence
By: Michael Conard Thank you for downloading my Zeller's Congruence program! This took a lot of trial and error, but I finally got it. Zeller's Congruence calculates what day of the week it is using arithmetic, I studied the formulas for a while and have been able to calculate it on paper and in my head in under 20 seconds now. It is extremely efficient, and I prefer it to a calendar.
egyptian1.zip2k12-08-05File is not ratedEGYPTIAN FRACTIONS
AEGYPT2: This program decomposes fractions into sums of unit fractions: Egyptian fractions. The ancient Egyptians did not write 5/8, but 1/2+1/8, because they didn't have a system for the compact notation m/n, hence the name. They are presented, in general, in descending order, i.e. the denominators get smaller and smaller. The method in this program is to subtract the second biggest, or sometimes the third, or smaller, biggest unit fraction from the number that results in the remainder getting a smaller denominator. This makes it likely, but not necessary, that the next such unit fraction to subtract is bigger than the previous. This is repeated until the remainder itself is a unit fraction. With this method the unit fractions does not become so small as with Fibonnaci's method. When finished, the program pauses a list with the unit fractions, and then shows a list with their denominators. AEGYPT3: This program is different, but works in principle the same way. However it gives the same answers. At least for the numbers I've checked. AEGYPT4: This program is a modification of Fibonnaci's method. It gives pretty much the same answers as the other programs. But here the unit fractions become smaller and smaller in general. AEGYPT0: This program uses Fibonnaci's method. It is submitted for comparison. There is a link to a page on the subject in the text file.
egyptian.zip2k12-08-05File is not ratedEGYPTIAN FRACTIONS
EGYPTIAN: This program decomposes fractions into sums of unit fractions. For example 5/8 is decomposed into 1/2+1/8. The ancient Egyptians did not write 5/8, but 1/2+1/8, because they didn't have a system for the compact notation m/n, hence the name. The program uses a modified version of Fibonnaci's method. When finished, the program pauses a list with the unit fractions, and then shows a list with their denominators. AEGYPT: This program is also a modification of Fibonnaci's method: The program seeks to finish earlier by counting up the unit fraction it is about to subtract with 10 units, and if it finds that the inverted remainder would make an even integer prior to those 10 units, it goes ahead with it. Otherwise it continues as usual with Fibonnaci's method. AEGYPT1: This is a slightly more complicated version, but it will produce the same unit fractions as EGYPTIAN. AEGYPT0: This program uses Fibonnaci's method. It is submitted for comparison. There is an url to a page on the subject in the text file.

It is meant to help in school with various types of fractions. I would be grateful for any comments, suggestions etc.
frac1.zip1k10-08-16File is not ratedFractions
This file contains two programs and a textfile: CFrac1 is a small and fast program that reduces rational values. Its capacity is much better than the built in >Frac. The built in program has a largest denominator of 9999 and it can't handle a fraction like 8620/4311. CFrac1 can give correct answers for values of the numerator and denominator up to 40- 50 000. The answer is given both as improper fraction and as a mixed number, when the value is bigger than one. Can be used for quickly separating rational numbers from irrational, if the rational numbers don't have a too big fraction. Frac1 is a program aimed for bigger fractions where you input one term at a time. The numbers can have a numerator and denominator of ten digits.
factorfast.zip1k10-06-14File is not ratedFactor FAST v 2.3.5
As you noticed, there's special emphasis on the FAST. Although it doesn't seem too great at first, the best thing about this program is that once it finds half of the factors, it automatically calculates the second half in a matter of milliseconds. I belive this is one of the only programs that can factor a million in under 45 seconds. If you forget what the factors are, just check the list FACTR, and it'll show you all of them! This will be a great addition to your calculator.
quotientv1.1.zip1k10-06-04File is not ratedQuotient v1.1
Converts a fraction into a decimal. This program was made by me so long ago, but I dug it out of some backup file; my 8451C 5KI115 (BASIC SKILLS) were pretty lousy, but I optimized what I could in about 30 secs.
perfect1.zip2k10-03-31File is not ratedPerfect Numbers
The first seven perfect numbers are: 6, 28, 496, 8128, 33550336, 8589869056, and 137438691328. There are presently 47 known such numbers, wich are defined by the fact that the sum of their divisors is twice the number itself. For example 6 has the divisors: 1, 2, 3, 6, wich adds up to 12. There is for now no known odd number that is perfect. But it has been proven that it has to be bigger than 10^300, if it exists. All even perfect numbers are on the form: 2^(p-1)(2^p-1), where p and 2^p-1 are prime numbers. I have made four small programs to demonstrate these numbers.

This is an updated version of my previous Goldbach conjecture. This program finds a pair of prime numbers that add up to a given even number greater than 4. Every even number ever checked has been the sum of at least two primes, but nobody has been able to prove that it is always true. Presently, there is a $1 million reward for discovering the proof.
decsimp.zip3k09-07-27File is not ratedFour Decimal Simplifiers
ABILIFY: This program converts decimals to exact forms. It can convert to a multiple of a square root, a multiple of pi, a multiple of e, or to a fraction. All results are simplified. It can also do this for complex numbers. The program sifts the information in the Ans-memory, showing only what is relevant. ADVANCE: This program is identical with the one above, except that it can also handle a square root of a multiple: not just the numerator is reduced, but also the denominator. ADAPT: This program presents the result of a square root like ABILIFY if the answer will then take up the same space or less, else the result is presented like ADVANCE. Otherwise the program is identical with ADVANCE. ADECSMP: This program presents the result of a square root in both ways if the denominator within the root is bigger than one. Other than that it is identical with ADVANCE. The programs are 639, 710, 776 resp. 743 bytes on your calculator.
primefactor.zip1k09-06-23File is not ratedPrime Factorer

matmzipper.zip1k03-06-02File is not ratedExact Values For Extremely Large Integer Multiplication (PU
This program allows for extremely high integer multiplication. The largest integer you can display exactally on the TI-83+ is 9999999999 of 10^10-1. The largest value you can reach period, before getting an overflow error is 10^99. This program calculated the exact value of (10^277-1)^2. Using that same formula, the overflow point for the TI-92+ is (10^308-1)^2. This program //greatly// expands the multiplicative capabilities for the calculator. However, there are a few limitations. You can only multiply integers, and you have to type them out exactally. Yes, I entered 277 9's by hand. Twice. The program is pretty small, 728 bytes. Pretty fast too, it squared a google in less than 5 minutes. When you run the program, it will ask for the two numbers, then it will begin displaying the percent multiplied as it works. Once it completely multiplies the number, it takes another moment or 2 to convert it to a displayable format. Then it displays it. If it flows off the edge, just scroll. I have big plans for this program, and using the (Un)Archive functions, I hope to expand the capacity even more. See how far you can take it, my calculator is pretty bad. Push the envelope.
