    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](https://www.chedong.com/phpMan.php/perldoc/POSIX%3A%3Afloor/markdown)" and "[POSIX::ceil](https://www.chedong.com/phpMan.php/perldoc/POSIX%3A%3Aceil/markdown)" functions will
            serve you better than will "int".
