This library uses assembly code to compute all operations with proper roundings, and currently ONLY works on intel processors. It supports Linux, Windows and MacOS, with gcc and clang. Unfortunately, the Intel processor does not properly round trigonometric functions so this library cannot be used whenever proved correct enclosures are needed.
