Result: DiscardedThe test labeled "Casting" was the faster by 0.0251 seconds, (5.373% faster)
The Casting test took 0.4415 seconds.
The is_float test took 0.4665 seconds.
Each test case ran 20 random code order iterations consisting of 121,494 loops for a total of 2,429,880 runs.
- Line execution difference (0.000010) milliseconds.
- Avg difference (1.253) milliseconds per 121,494 loops.
- Total difference 25.07 milliseconds for 2,429,880 loops
The iteration variablity for Code 1 was (3.9650) milliseconds and Code 2 was (1.7703) 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'];
