Result: DiscardedThe test labeled "is_float" was the faster by 0.0167 seconds, (2.247% faster)
The is_float test took 0.725 seconds.
The Casting test took 0.7416 seconds.
Each test case ran 20 random code order iterations consisting of 154,728 loops for a total of 3,094,560 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.833) milliseconds per 154,728 loops.
- Total difference 16.67 milliseconds for 3,094,560 loops
The iteration variablity for Code 1 was (9.0974) milliseconds and Code 2 was (10.6023) 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'];
