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.)
