Synopsis
number = RandomGenerator:random( )
Arguments
None.
Returns
number number- The pseudo-random number.
Function
Get uniformly distributed pseudo-random integer number within [1, max].
Synopsis
number = RandomGenerator:random( max )
Arguments
number max- The maximum possible value it should return.
Returns

Function
Get uniformly distributed pseudo-random integer number within [min, max].
Synopsis
number = RandomGenerator:random( min, max )
Arguments
number min- The minimum possible value it should return.
number max- The maximum possible value it should return.
Returns
number number- The pseudo-random integer number.
Notes
When using the 2nd and 3rd variant, numbers passed will be rounded, thus, RandomGenerator:random(0, 76.767) may return 77
