Result: DiscardedThe test labeled "Casting" was the faster by 0.0385 seconds, (3.402% faster)
The Casting test took 1.0937 seconds.
The is_float test took 1.1322 seconds.
Each test case ran 20 random code order iterations consisting of 281,072 loops for a total of 5,621,440 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (1.926) milliseconds per 281,072 loops.
- Total difference 38.52 milliseconds for 5,621,440 loops
The iteration variablity for Code 1 was (6.1178) milliseconds and Code 2 was (3.0386) 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'];
