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.
