This module provides predicates for generating pseudo-random numbers

Usage and interface (random)

Documentation on exports (random)

PREDICATE: random/1:

random(Number)

Number is a (pseudo-) random number in the range [0.0,1.0]

PREDICATE: random/3:

random(Low, Up, Number)

Number is a (pseudo-) random number in the range [Low, Up]

Usage 1: random(+int, +int, -int)

PREDICATE: srandom/1:

srandom(Seed)

Changes the sequence of pseudo-random numbers according to Seed. The stating sequence of numbers generated can be duplicated by calling the predicate with Seed unbound (the sequence depends on the OS).
