Here are some calculators ive written, calc.zip [13k] is a simple command line multiprecision calculator with a few number theoretic functions added in (more later). Here is the ansi C source code, calcsrc.zip [32k]. the mutiprecision arithmetic is from Knuth and the number algorithms from "Prime Numbers", by Richard Crandall and Carl Pomerance. note: mini calculator now uses the incompatible c library! numcalc.zip [420k] is a windows based fixed point calculator that works to 100 digits, i wrote ages ago. it has a number of tabs for different number theoretical modes, but i got bored and you will see a lot of missing buttons where functions were to go. internally, it uses the MIRACL library. scicalc.exe is a command line scientific calculator. |
