// Package gmp implements multi-precision arithmetic (big numbers).
|
|
//
|
|
// This package provides a drop in replacement for Go's built in
|
|
// math/big integer package using the GNU Multiprecision Library (GMP)
|
|
// to implement the operations.
|
|
//
|
|
// GMP is very much faster than Go's math/big however it is an
|
|
// external C library with all the problems that entails (cgo,
|
|
// dependencies etc)
|
|
//
|
|
// The following numeric types are supported:
|
|
//
|
|
// - Int signed integers
|
|
// - Rat rational numbers are NOT yet supported
|
|
//
|
|
// Methods are typically of the form:
|
|
//
|
|
// func (z *Int) Op(x, y *Int) *Int (similar for *Rat)
|
|
//
|
|
// and implement operations z = x Op y with the result as receiver; if it
|
|
// is one of the operands it may be overwritten (and its memory reused).
|
|
// To enable chaining of operations, the result is also returned. Methods
|
|
// returning a result other than *Int or *Rat take one of the operands as
|
|
// the receiver.
|
|
//
