int
- 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 will int().
