Result: DiscardedThe test labeled "Casting" was the faster by 0.0133 seconds, (2.073% faster)
The Casting test took 0.628 seconds.
The is_float test took 0.6413 seconds.
Each test case ran 20 random code order iterations consisting of 130,908 loops for a total of 2,618,160 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.665) milliseconds per 130,908 loops.
- Total difference 13.29 milliseconds for 2,618,160 loops
The iteration variablity for Code 1 was (9.0460) milliseconds and Code 2 was (9.8684) milliseconds. The lower and the closer together there values are the more accurate the results are.
The first test, "is_float", was:
$a = is_float($GLOBALS['test']);
The second test, "Casting", was:
$a = (float) $GLOBALS['test'] === $GLOBALS['test'];
