lcg_value Combined linear congruential generator &reftitle.description; floatlcg_value 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. &reftitle.returnvalues; A pseudo random float value in the range of (0, 1) &reftitle.seealso; rand mt_rand
