Result: Discarded

The test labeled "Casting" was the faster by 0.0652 seconds, (5.574% faster)

Casting 100%
is_float 94.426%

The Casting test took 1.1039 seconds.
The is_float test took 1.1691 seconds.


Each test case ran 20 random code order iterations consisting of 272,445 loops for a total of 5,448,900 runs.

  • Line execution difference (0.000012) milliseconds.
  • Avg difference (3.258) milliseconds per 272,445 loops.
  • Total difference 65.16 milliseconds for 5,448,900 loops

The iteration variablity for Code 1 was (8.3088) milliseconds and Code 2 was (5.8478) 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'];
