Cast vs is_float

Run this test again Return to test menu

Result: Discarded

The test labeled "Casting" was the faster by 0.0251 seconds, (5.373% faster)

Casting 100%
is_float 94.627%

The Casting test took 0.4415 seconds.
The is_float test took 0.4665 seconds.


Each test case ran 20 random code order iterations consisting of 121,494 loops for a total of 2,429,880 runs.

  • Line execution difference (0.000010) milliseconds.
  • Avg difference (1.253) milliseconds per 121,494 loops.
  • Total difference 25.07 milliseconds for 2,429,880 loops

The iteration variablity for Code 1 was (3.9650) milliseconds and Code 2 was (1.7703) 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'];
