random, srandom

Purpose: random() generates and srandom() initializes pseudo random numbers. random() has no parameters, the seed parameter of srandom() must be of type integer. srandom() initializes a new sequence of pseudo random numbers. A sequence is repeatable if it is initialized with the same seed value.

Return Values: random() returns a pseudo random number in the range of 0 to (2³¹)-1. srandom() does not return a result.

Example:

input:	resulting output:
<let srandom(13); ? random();? " ";? random()> <let srandom(257);? random();? " ";? random()> <let srandom(13);? random();? " ";? random()>	1358590890 733184381 1256888895 1373592409 1358590890 733184381
