AMD Math Library (LibM)
AMD LibM is a software library containing a collection of basic math functions optimized for x86-64 processor based machines. It provides many routines from the list of standard C99 math functions.
AMD LibM is a C library, which users can link in to their applications to replace compiler-provided math functions. Generally, programmers access basic math functions through their compiler, but those who want better accuracy or performance than their compiler’s math functions can use this library to help improve their applications.
