Historical ResultsBased on (5) saved test runs, The test labeled "Casting" was (on average) the faster by 0.0006 seconds, (0.066% faster)
The Casting test took 0.9713 seconds.
The is_float test took 0.972 seconds.
Each test case ran 20 random code order iterations consisting of 243,320 loops for a total of 4,866,396 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.000) milliseconds per 243,320 loops.
- Total difference 0.65 milliseconds for 4,866,396 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'];
