rand
rand num
Returns a random fractional number between 0 and the value of
num.
(numshould be positive.) If
num is omitted, the function returns a
value between 0 and 1 (including 0, but excluding 1). See also srand .
To get an integral value, combine this with int, as in:
$roll = int(rand 6) + 1; # $roll is now an integer between 1 and 6
