Historical ResultsBased on (2) saved test runs, The test labeled "Casting" was (on average) the faster by 0.0154 seconds, (1.516% faster)
The Casting test took 1.0029 seconds.
The is_float test took 1.0183 seconds.
Each test case ran 20 random code order iterations consisting of 205,678 loops for a total of 4,113,560 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 205,678 loops.
- Total difference 15.43 milliseconds for 4,113,560 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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'];
