#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 towards0, 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, thesprintf,printf, or thePOSIX::floor andPOSIX::ceil functions will serve you better than willint. Moreover,int 'Inf' produces Inf (see"Special floating point: infinity (Inf) and not-a-number (NaN)" in perldata for explanation), but so do all the alternative methods mentioned above.
