Descrierea

resource 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.
