Cast vs is_float

Run this test again Return to test menu

Result: Discarded

The test labeled "Casting" was the faster by 0.0096 seconds, (1.478% faster)

Casting 100%
is_float 98.522%

The Casting test took 0.6411 seconds.
The is_float test took 0.6507 seconds.


Each test case ran 20 random code order iterations consisting of 144,456 loops for a total of 2,889,120 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.481) milliseconds per 144,456 loops.
  • Total difference 9.62 milliseconds for 2,889,120 loops

The iteration variablity for Code 1 was (4.1461) milliseconds and Code 2 was (4.9372) 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'];
