No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "float" was the faster by 0.0165 seconds, (1.558% faster)

float 100%
integer 98.442%

The float test took 1.0395 seconds.
The integer test took 1.0559 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 292,949 loops for a total of 5,858,980 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.823) milliseconds per 292,949 loops.
  • Total difference 16.45 milliseconds for 5,858,980 loops

The iteration variablity for Code 1 was (2.0078) milliseconds and Code 2 was (2.2773) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "float", was:

$GLOBALS['dummy'] = 0.0;
for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy'] += $GLOBALS['dummy_float'];

The second test, "integer", was:

$GLOBALS['dummy'] = 0;
for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy'] += $GLOBALS['dummy_int'];
