This file contains 13 programs for the CASIO fx CG50: AFRAC, a program that uses continued fraction, and can give you a good approximation, as well as the exact value for denominators well above a million. APRIME: A prime finder which divides out all even numbers as well as numb…
This program solves polynomials using the Solve(-function. To avoid getting the same value it divides the function with the factors as it goes, Solve(y1,x, -100,100)->A, Solve(y1/(x-A),x, -100,100)->B. It can repeat this process up to four times, but it can also combine the root…
These two programs aim to find two prime numbers that have been multiplied with each other. PRIME6 is as simple as possible, and PRIME6D is a demo version. The idea is to find a number that is close to a multiple to one of the primes: plus, minus 167. To do that the program typi…
Update of the text file. The programs are the same.This file contains five programs about roots. QUADRA gives the roots of the second degree equation, plus the Discriminant and the formulas involved. A3 gives the numerical solution to the third degree equation. RADICAL gives the…
Update: This program is an experiment, but it is very fast compared to SOLVERY, for most polynomials, and also gives you the integer second degree factors, wether their roots are real or imaginary. Instead of going about to analytically test for second degree factors, it tries t…
Update: Fixed a bug in ADDMULT1. ADDMULT uses CFRAC, and ADDMULT1 uses Euclid’s algorithm to find the divisors. These programs are built on the fact that second degree equations with rational roots can be solved by dividing the coefficients in Ax^2+Bx+C=0, with A, and then sele…
This program gives the exact values for numbers like: 4(√-8+12i)-16), 6(√(8-12i)+8), i.e. only square roots this time. If the program also was to be able to handle third- and fourth-roots, I would have had to handle massive complications and I wanted to keep the size down, it is…
Update: This is the original SYNDIV, with 1916 bytes. The previous version with 1840 bytes was buggy. I am including it in the file since you are still downloading it, trying to figure out which version is best. Well, here they are, both of them. As you will see, SYNDIV1 is the …
This program gives you the exact values for expressions like, 4(√19-3), 4(√192+16), and also similar expressions with third- and fourth roots. I know that the CG 50 has a program built in for this, but it isn’t always working, and you can’t use it in retrospect. The program stri…
