Result: Discarded

The test labeled "is_float" was the faster by 0.0205 seconds, (2.867% faster)

is_float 100%
Casting 97.133%

The is_float test took 0.6954 seconds.
The Casting test took 0.7159 seconds.


Each test case ran 20 random code order iterations consisting of 134,432 loops for a total of 2,688,640 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.026) milliseconds per 134,432 loops.
  • Total difference 20.53 milliseconds for 2,688,640 loops

The iteration variablity for Code 1 was (6.4771) milliseconds and Code 2 was (7.4405) 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'];
