Description
This function is an interface to the simple pseudo-random generator function rand provided by ANSI C. (No guarantees can be given for its statistical properties.)
When called without arguments, returns a uniform pseudo-random real number in the range [0,1). When called with an integer number m, math.random returns a uniform pseudo-random integer in the range [1, m]. When called with two integer numbers m and n, math.random returns a uniform pseudo-random integer in the range [m, n].
(number) = math.random(n,u)
Parameters
n: (number) upper limit if only n provided, lower limit if u also provided optional
u: (number) upper limit optional
Return values
Returns (number) pseudo random number
