Result: DiscardedThe test labeled "Casting" was the faster by 0.0592 seconds, (8.699% faster)
The Casting test took 0.6213 seconds.
The is_float test took 0.6805 seconds.
Each test case ran 20 random code order iterations consisting of 168,801 loops for a total of 3,376,020 runs.
- Line execution difference (0.000018) milliseconds.
- Avg difference (2.960) milliseconds per 168,801 loops.
- Total difference 59.20 milliseconds for 3,376,020 loops
The iteration variablity for Code 1 was (4.2993) milliseconds and Code 2 was (1.4795) 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'];
