Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Syntax

r = impureRandomInteger(id, imin=1, imax=Modelica.Constants.Integer_inf);

Description

Returns an Integer random number in the range imin ≤ random ≤ imax with the xorshift1024* algorithm, (the random number in the range 0 ... 1 returned by the xorshift1024* algorithm is mapped to an Integer number in the range imin ... imax). The dummy input Integer argument id must be the output argument of a call to function initializeImpureRandom, in order that the sorting order is correct (so that impureRandomInteger is always called after initializeImpureRandom). For every call of impureRandomInteger(id), a different random number is returned, so the function is impure.
