lcg_value
Combined linear congruential generator
(PHP 4, PHP 5)
lcg_value() returns a pseudo random number in the range of (0, 1). The function combines two CGs with periods of 2^31 - 85 and 2^31 - 249. The period of this function is equal to the product of both primes. Code Examples / Notes » lcg_valuerok kralj gmail com
An elegant way to return random float between two numbers: <?php function random_float ($min,$max) { return ($min+lcg_value()*(abs($max-$min))); } ?> |
