'' GMP is a free library for arbitrary precision arithmetic, operating
|
|
on signed integers, rational numbers, and floating point numbers.
|
|
There is no practical limit to the precision except the ones implied
|
|
by the available memory in the machine GMP runs on. GMP has a rich
|
|
set of functions, and the functions have a regular interface.
|
|
|
|
The main target applications for GMP are cryptography applications
|
|
and research, Internet security applications, algebra systems,
|
|
computational algebra research, etc.
|
|
|
|
GMP is carefully designed to be as fast as possible, both for small
|
|
operands and for huge operands. The speed is achieved by using
|
|
fullwords as the basic arithmetic type, by using fast algorithms,
|
|
with highly optimised assembly code for the most common inner loops
|
|
for a lot of CPUs, and by a general emphasis on speed.
|
|
|
|
GMP is faster than any other bignum library. The advantage for GMP
|
|
increases with the operand sizes for many operations, since GMP uses
|
|
asymptotically faster algorithms.
