From:
Operating system: fedora 13
PHP version: 5.3.3
Package: Scripting Engine problem
Bug Type: Bug
Bug description:"less than" operator returning true even if numbers are equal
Description:
------------
I am using the following PHP version:
PHP 5.3.3 (cli) (built: Jul 22 2010 15:57:00)
Info: re-typing everything to (float), (double) or "no type specified" does
not fix the problem.
Test script:
---------------
<?
$min=(float)44;
$max=(float)54545;
$step=(float)($max-$min)/10;
if($step && $step>0)
{
$i=$min;
while($i<$max)
{
echo($i." < $max ");
var_dump($i,$max,$step);
echo("<br />");
$i+=$step;
}
}
if($i>$max) echo("WHAT?"); ?>
Expected result:
----------------
44 < 54545 float(44) float(54545) float(5450.1)
5494.1 < 54545 float(5494.1) float(54545) float(5450.1)
10944.2 < 54545 float(10944.2) float(54545) float(5450.1)
16394.3 < 54545 float(16394.3) float(54545) float(5450.1)
21844.4 < 54545 float(21844.4) float(54545) float(5450.1)
27294.5 < 54545 float(27294.5) float(54545) float(5450.1)
32744.6 < 54545 float(32744.6) float(54545) float(5450.1)
38194.7 < 54545 float(38194.7) float(54545) float(5450.1)
43644.8 < 54545 float(43644.8) float(54545) float(5450.1)
49094.9 < 54545 float(49094.9) float(54545) float(5450.1)
Actual result:
--------------
44 < 54545 float(44) float(54545) float(5450.1)
5494.1 < 54545 float(5494.1) float(54545) float(5450.1)
10944.2 < 54545 float(10944.2) float(54545) float(5450.1)
