Historical Results

Based on (3) saved test runs, The test labeled "float" was (on average) the faster by 0.0195 seconds, (2.777% faster)

float 100%
integer 97.223%

The float test took 0.683 seconds.
The integer test took 0.7025 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 187,023 loops for a total of 3,740,460 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 187,023 loops.
  • Total difference 19.51 milliseconds for 3,740,460 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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'];
