<?php var_dump(0.0000); var_dump(0.0000 === 0.0000000); var_dump(0.0000 == '0'); $var = 0.0000; var_dump(empty($var)); $var = '0.0000'; var_dump(empty($var)); var_dump($var > 0); $var = '1.0000'; var_dump($var > 0); echo intval($var);

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
