Third order equations
---------------------------------------------------------------
Version: 1.0, 980205
Creator: Daniel Bergman.
Description: The program solves the equation x^3+ax+b=0.
Comments: "3\/" is the third order root, "\/" is the square root.
Known bugs: The program can't solve equations with more than one root.
If such an equation is being inputed, the program terminates.
