简介

These functions allow for arbitrary-length integers to be worked with using the GNU MP library.

注意:

Most GMP functions accept GMP number arguments. These are shown in this documentation as GMP objects. Most of these functions will also accept numeric and string arguments, so long as it is possible to convert the latter to a number. Also, if there is a more performant function that can operate on the arguments (integers only), then it will be used instead (this is done transparently). See also the gmp_init() function.

注意:

The arithmetic, bitwise, and comparison operators may be used with the GMP objects returned from gmp_init() and other GMP functions.
