No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "integer" was the faster by 0.0095 seconds, (1.804% faster)

integer 100%

float 98.196%

The integer test took 0.5166 seconds.
The float test took 0.5261 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 134,865 loops for a total of 2,697,300 runs.

Line execution difference (0.000004) milliseconds.
Avg difference (0.474) milliseconds per 134,865 loops.
Total difference 9.49 milliseconds for 2,697,300 loops

The iteration variablity for Code 1 was (2.8484) milliseconds and Code 2 was (1.9105) 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'];
