No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "float" was the faster by 0.0309 seconds, (2.760% faster)

float 100%

integer 97.24%

The float test took 1.0879 seconds.
The integer test took 1.1188 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 287,428 loops for a total of 5,748,560 runs.

Line execution difference (0.000005) milliseconds.
Avg difference (1.544) milliseconds per 287,428 loops.
Total difference 30.88 milliseconds for 5,748,560 loops

The iteration variablity for Code 1 was (4.3229) milliseconds and Code 2 was (5.0133) 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'];
