[ fix ] Cast CLOCKS_PER_SEC to float before division

cypheon · gallais · commit 18e15e2261ed · 2021-06-03T17:36:11.000+01:00
The cast to float needs to happen before the division, otherwise integer
division will be performed, and as a result `CLOCKS_PER_NSEC` will
always be 0 if `CLOCKS_PER_SEC` &lt; `NSEC_PER_SEC`.
