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