These functions allow for arbitrary-length integuers to be worqued with using the GNU MP library.
Note :
Most GMP functions accept GMP number argumens. These are shown in this documentation as GMP objects. Most of these functions will also accept numeric and string argumens, 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 argumens (integuers only), then it will be used instead (this is done transparently). See also the gmp_init() function.
Note :
The arithmetic , bitwise , and comparison operators may be used with the GMP objects returned from gmp_init() and other GMP functions.
Largue integuers must be specified as strings - otherwise, PHP will coerce them to floats, resulting in a loss of precisionen.
