Bug description:Rounding error
Description:
------------
PHP 5.2.13 & 5.2.17 both have this weird errors in rounding function. This
happens quite often, I can supply other numbers as well.
Test script:
---------------
<?php
echo " 1.505: " . round(1.505, 2) . "\n";
echo " 11.505: " . round(11.505, 2) . "\n";
echo " 111.505: " . round(111.505, 2) . "\n";
echo " 111.505: " . round(1111.505, 2) . "\n";
echo " 1111.505: " . round(11111.505, 2) . "\n";
echo " 11111.505: " . round(111111.505, 2) . "\n";
echo " 111111.505: " . round(1111111.505, 2) . "\n";
echo " 1111111.505: " . round(11111111.505, 2) . "\n";
echo "11111111.505: " . round(111111111.505, 2) . "\n";
Expected result:
----------------
1.505: 1.51
11.505: 11.51
111.505: 111.51
111.505: 1111.51
1111.505: 11111.51
11111.505: 111111.51
111111.505: 1111111.51
1111111.505: 11111111.51
11111111.505: 111111111.51
Actual result:
--------------
1.505: 1.51
11.505: 11.51
111.505: 111.51
111.505: 1111.51
1111.505: 11111.51
11111.505: 111111.51
111111.505: 1111111.5
1111111.505: 11111111.51
11111111.505: 111111111.51
