Random number seed for a MathMap


This attribute, which may take any integer value, determines the sequence of random numbers produced by the random number functions in MathMap expressions. It is set to an unpredictable default value when a MathMap is created, so that by default each MathMap uses a different set of random numbers.

If required, you may set this Seed attribute to a value of your choosing in order to produce repeatable behaviour from the random number functions. You may also enquire the Seed value (e.g. if an initially unpredictable value has been used) and then use it to reproduce the resulting sequence of random numbers, either from the same MathMap or from another one.

Clearing the Seed attribute gives it a new unpredictable default value.



All MathMaps have this attribute.
