Bug description: round() does 5.045 to 5.04 instrad of 5.05
Description:
------------
I am using a webhosting service of bbdsoft (www.firmos.net) so I don't
know exact OS and configuration of PHP.INI, but this bug is
independent of any config or OS, it's about round() function - it has a
big bug rounding floats!!
All the details and what's have to be is written below in the source code
and it's comments:)
Well, I saw other reports, and I think YOU SHOULD FIX THIS IN ANY CASE AND
AS FAST AS POSSIBLE!!!
Reproduce code:
---------------
// at the start of the return code these variables has values:
$skerd_svoris = 1;
$rows_kriu_kain00[0] = 5;
$rows_kriu_kkoef[0] = 0.9;
// return code:
return sprintf("%1.2f",
round($skerd_svoris*round($rows_kriu_kain00[0]*(1+($rows_kriu_kkoef[0]/100)),
2), 2));
// if the code is changed to:
// return sprintf("%1.2f",
round($skerd_svoris*round($rows_kriu_kain00[0]*(1+($rows_kriu_kkoef[0]/100))+0.000001,
2), 2));
// all goes OK; so the problem is that if the number is 5.045, rounded it
will be 5.04, but if it is 5.045001 - rounded it will be 5.05. I think You
understood what I want to say:)
Expected result:
----------------
5.05
Actual result:
--------------
5.04
