7.5.19.1 The Default Random Source

Function: random-integer n

Return a random number between zero (inclusive) and n (exclusive), using the default random source. The numbers returned have a uniform distribution.

Function: random-real

Return a random number in (0,1), using the default random source. The numbers returned have a uniform distribution.

Function: default-random-source

A random source from which random-integer and random-real have been derived using random-source-make-integers and random-source-make-reals (see section Obtaining random number generator procedures for those procedures). Note that an assignment to default-random-source does not change random-integer or random-real; it is also strongly recommended not to assign a new value.
