Introduction 1.1. Project/Component Working Name: GNU MP arbitrary precision arithmetic library 1.2. Name of Document Author/Supplier: Author: Darren Moffat 1.3 Date of This Document: 29 February, 2008 4. Technical Description Description of libgmp --------------------- GNU MP is a library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. It has a rich set of functions, and the functions have a regular interface. GNU MP is designed to be as fast as possible, both for small operands and huge operands. The speed is achieved by using fullwords as the basic arithmetic type, by using fast algorithms, with carefully optimized assembly code for the most common inner loops for lots of CPUs, and by a general emphasis on speed (instead of simplicity or elegance). OpenSolaris delivery -------------------- Note that the optional BSD libmp compatibility library is not provided since OpenSolaris already has a /usr/lib/libmp.so. The project team has no plans to replace the exist libmp (or the two other private bignum implementations used in crypto) by this one. Replacement of the others may not even be possible since GNU MP is released under LGPL. The optional C++ support is also not provided due to the well known ABI issues with providing C++ libaries on Solaris (g++ vs Sun C++), a future case may be submitted to provide the C++ libaries if there is sufficient demand and/or the ABI issue is resolved.
