Bug Type: Strings related
Operating System: Linux (SuSE 7.0)
PHP Version: 4.0.3pl1
New Comment:
This problem also exits in our application which runs on php-4.2.3.
We use 'setlocale' there to handle gettext translations. With LC_ALL
set by 'setlocale' all prices in the shopping basket and VAT
calculations with floats are 'calculated wrong'
Thanks for that hint.

unable to reproduce with latest version of PHP, please
upgrade and re-open if still a problem.

Changing the locale setting to a country that uses comma (,)
as the decimal seperator will stip off decimal places from
the float value in printf/sprintf. Example:
MySQL table:
create table test (
name varchar(100),
value float(16,2)
);
insert into test values ('bla', 3.789);
PHP code:
setlocale("LC_ALL", "de_DE");
// mysql_connect etc.
$row = mysql_fetch_array($result);
printf("%s: %.2f",
$row["name"], $row["value"]);
Result:
bla: 3.00
