I recently took up learning C and had a problem when trying to compile a program that called the pow() function and the sqrt() function. I thought those functions should have been in the math.h header file. My programs worked with the Microsoft compiler, but I would prefer to write programs for Linux. I have 3 computers with 3 different versions of Linux installed, but none of them have the math functions that I need (or that I know of at least). I have the versions of gcc that were included with Redhat 6.0, Redhat 6.1, and Mandrake 6.0. I was wondering if there is a new math.h file that I can download somewhere. If you know, please send me a link to it.   Thanks much,         Tom Filley         tafilley@home.com Â
