gmp_randomRandom number

설명

GMP gmp_random ([ int $limiter = 20 ] )

Generate a random number. The number will be between zero and the number of bits per limb multiplied by limiter. If limiter is negative, negative numbers are generated.

A limb is an internal GMP mechanism. The number of bits in a limb is not static, and can vary from system to system. Generally, the number of bits in a limb is either 16 or 32, but this is not guaranteed.

Warning: Do not use this function.

Use gmp_random_bits() or gmp_random_range() instead.

The documentation and the code for this function do NOT match, and in any case this function is quite useless.
