Result: Discarded

The test labeled "Casting" was the faster by 0.0592 seconds, (8.699% faster)

Casting 100%
is_float 91.301%

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'];
