Result: DiscardedThe test labeled "is_float" was the faster by 0.0173 seconds, (3.440% faster)
The is_float test took 0.4846 seconds.
The Casting test took 0.5019 seconds.
Each test case ran 20 random code order iterations consisting of 137,192 loops for a total of 2,743,840 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (0.863) milliseconds per 137,192 loops.
- Total difference 17.26 milliseconds for 2,743,840 loops
The iteration variablity for Code 1 was (0.3601) milliseconds and Code 2 was (1.4026) 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'];
