arithmetics and rational numbers

[antx]

Hello,

I am looking for libraries in order to compute advanced arithmetic operations (gcd...), and another one to implement rational numbers (I know it's easy but I'd like to avoid re-writing the class and operators)

Do someone know this kind of libraries ?

Thank you

You could try this:

http://gmplib.org/

It does rational numbers:

http://gmplib.org/manual/Rational-Number-Functions.html#Rational-Number-Functions

EDIT: C++ interface

http://gmplib.org/manual/C_002b_002b-Interface-Rationals.html#C_002b_002b-Interface-Rationals

Thank you, it seems perfect !

For those who speak french and would like to install it on a MS-windows system (not sure there will be a lot but...) :

It is a small program to compile it.
