- int EXPR
-
- int
- Returns the integer portion of EXPR. If EXPR is omitted, uses
$_. You
should not use this function for rounding: one because it truncates towards 0,
and two because machine representations of floating point numbers can sometimes produce
counterintuitive results. For example, int(-6.725/0.025) produces -268 rather
than the correct -269; that's because it's really more like -268.99999999999994315658
instead. Usually, the sprintf, printf, or the POSIX::floor
and POSIX::ceil functions will serve you better than will int().
