Historical ResultsBased on (1) saved test runs, The test labeled "is_float" was (on average) the faster by 0.008 seconds, (1.549% faster)
The is_float test took 0.5094 seconds.
The Casting test took 0.5174 seconds.
Each test case ran 20 random code order iterations consisting of 136,990 loops for a total of 2,739,800 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 136,990 loops.
- Total difference 8.02 milliseconds for 2,739,800 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'];
