Result: DiscardedThe test labeled "is_float" was the faster by 0.0198 seconds, (1.780% faster)
The is_float test took 1.0906 seconds.
The Casting test took 1.1104 seconds.
Each test case ran 20 random code order iterations consisting of 256,807 loops for a total of 5,136,140 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.988) milliseconds per 256,807 loops.
- Total difference 19.76 milliseconds for 5,136,140 loops
The iteration variablity for Code 1 was (2.4322) milliseconds and Code 2 was (3.3558) 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'];
