Result: DiscardedThe test labeled "Casting" was the faster by 0.0096 seconds, (1.478% faster)
The Casting test took 0.6411 seconds.
The is_float test took 0.6507 seconds.
Each test case ran 20 random code order iterations consisting of 144,456 loops for a total of 2,889,120 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.481) milliseconds per 144,456 loops.
- Total difference 9.62 milliseconds for 2,889,120 loops
The iteration variablity for Code 1 was (4.1461) milliseconds and Code 2 was (4.9372) 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'];
