Arirhmetic Programs
There are 4 different programs: fact() gives a factorisation in a list fi() gives Euler's function (fonction indicatrice d'Euler) inv(x,y) gives the smallest inverse of x modulo y, i.e: the smallest a so that a.x=1 modulo y pmod(a,b,c) which gives mod(a^b,c) but with very big numbers (like powmod by Zeljko Juric, but in basic). English and french version included. |

FACT 1.1 Large number factorials
This example program shows how to break the limitation where calculators have trouble producing factorials for large numbers. Most scientific calculators cannot handle more than 69!=1.711E98 because their displays can only handle two digit exponents. The TI-89 can handle up to 449! by default, because the display shows three digit exponents. This example program can handle up to 94851898540! |

Fracp
fracp(number) or fracp({number, precision}) is a function which calculates fractional approximation of a given number with required precision. If the argument of the function is a number then default precision (6 digits) is used. If the argument of the function is a list then first element of the list represents number and second element precision (1...12). Precision n indicates that the decimal representation of the fraction is exact at least in first n digits. |
