Description
Generate and return a pseudo random number. The random number sequence is guaranteed to be consistent across devices for a given seed.
If bounds aren't specified, the function will return a floating point number between 0 and 1. If one bound is specified, the function will return an integer number between 1 and that bound (inclusive). If both bounds are specified, the function will return an integer between bound1 and bound2. bound2 must be greater than bound1.
() = Core.random(generator,bound1,bound2)
Parameters
generator: (number) PRNG algorithm to use, use 0 for default engine (MT19937) optional
bound1: (number) First bound of the range returned number must be in optional
bound2: (number) Second bound of the range returned number must be in optional
Return values
Returns () random number
