impure functionimpureRandomInteger
Impure random number generator for integer values (with hidden state vector)
Extends from Modelica.Icons.Function (Icon for functions).
Information
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.
