(description
|
|
"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.")

"The GNU MPFR library is a C library for multiple-precision

The main goal of MPFR is to provide a library for multiple-precision

floating-point computation which is both efficient and has a well-defined

semantics. It copies the good ideas from the ANSI/IEEE-754 standard for

double-precision floating-point arithmetic (53-bit mantissa).")

"GNU MPC is a C library for the arithmetic of complex numbers with
|
|
arbitrarily high precision and correct rounding of the result. It extends
|
|
the principles of the IEEE-754 standard for fixed precision real floating
|
|
point numbers to complex numbers, providing well-defined semantics for
|
|
every operation. At the same time, speed of operation at high precision
|
|
is a major design goal. The library is built upon and follows the same
|
|
principles as GNU MPFR.")
