The Random function returns a random non-negative whole number within a finite range.
|result = Random( [ minOrMax ] [, [ max ] ] [, seed ] ] )|
When a seed is not specified for the first use of the random function, then an arbitrary seed value will be automatically used. This arbitrary value is usually obtained from the system's internal clock.
Portability note: different implementations can use a different internal random number generator. The sequence of numbers based on a random number seed may differ among these implementations.
Note: the difference between the maximum and minimum values can not exceed 100000.
say Random() -- shows a number between 0 and 999, with an arbitrary seed
say Random( 1 ) -- shows a number between 0 and 1, a coin flip with an arbitrary seed
say Random( 1, 6 ) -- shows a number between 1 and 6, with an arbitrary seed
say Random( 1, 6, 2002 ) -- shows a number between 1 and 6, with a specific seed
