I am sure this has been asked before but I was unable to find it. I am working on a math program and figured hey lets use c++ everything is great until I start programing for factorials. Well in short does anyone know of a library or package for dev C++ or .net that allows me to have integers greater then the oh so high long int. If not does anyone know how to get unsigned int 32 to work with the % fuction. But that still will only cover me for a bit I really could use a library that has all the functions that a long int would have just i need it to float.

Thanks in advance,
