- 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 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().
