System Class random-state

Class Precedence List:

Description:

A random state object contains state information used by the pseudo-random number generator. 12.9.0 1 The pseudo-random numbers in a random number series are \term{implementation-dependent}, but the distribution of the numbers should machine-independent.The nature of a random state object is implementation-dependent. It can be printed out and successfully read back in by the same implementation, but might not function correctly as a random state in another implementation.

12.9.0 20 A recommended way to implement \thetype{random-state} is effectively to use the machinery for \macref{defstruct}.

12.9.0 18Implementations are required to provide a read syntax for objects of type random-state, but the specific nature of that syntax is implementation-dependent.
