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().
