int - get the integer portion of a number
int EXPR
int
Returns the integer portion of
EXPR. If
EXPR is omitted, uses
$_. You should not use this for rounding, because it truncates towards 0, and because machine representations of floating point numbers can
sometimes produce counterintuitive results. Usually sprintf() or printf(), or the POSIX::floor or POSIX::ceil functions, would serve you better.
