<?php printf("%0.20f\n", 1.37601); printf("%0.20f\n", 1.37601 + 0.00250); echo "\n"; printf("%0.20f\n", 0.2); printf("%0.20f\n", 0.3); var_dump(0.3 == 0.1+0.1+0.1)

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
