Bug description: Detail
Description:
------------
Is anyone can help me about the code below . Here is I am collecting
values according to increment value between number ranges.
My first example never hits the end point although the end is in range but
second hits the range or third.
Why php treats numbers differently or cannot understand the last value is
still below end point.
Can anyone tell me.
Reproduce code:
---------------
<?PHP
function increment ($start, $end, $increment_val)
{
$ret_arry = array ();
$temp = $start;
if ( ($start+$increment_val) <= $end )
{
do{
echo " " . $temp . "," ;
$temp = $temp + $increment_val;
}while ( $temp <= $end );
}
else
{
echo "Can not do This";
}
}
$start = "1.0";
$end = "1.6";
$increment_val = "0.1";
increment($start, $end, $increment_val);
$start = "1.0";
$end = "4.9";
$increment_val = "0.1";
echo "\n";
increment($start, $end, $increment_val);
?>
Expected result:
----------------
1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6
1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4,
2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9,
4, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9,
Actual result:
--------------
1.0, 1.1, 1.2, 1.3, 1.4, 1.5,
1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4,
2.5, 2.6, 2.7, 2.8, 2.9, 3, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9,
4, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9,
