rand EXPR
rand
Returns a random fractional number greater than or equal to 0 and less than the value of
EXPR.
(EXPR should be positive.) If
EXPR is omitted, the value 1 is used. Automatically calls srand() unless srand() has already been called. See also srand().
(Note: If your rand function consistently returns numbers that are too large or too small, then your version of Perl was probably compiled with the wrong number of
RANDBITS.)
