I didn't hear anything anymore, so I am just curious if this was picked
up... Thanks, Jonathan

Hi somehow it has to do with converting 'numberic'-strings to floats as
the script below shows:
<?
$rate1 = 1.123;
$amount1 = 5;
$rate2 = "1.123";
$amount2 = "5";
// set locale to English to handle the floatingpoints correctly
// first calculation with floats
setlocale (LC_ALL, 'en_US');
echo "This should be correct:<br><br>";
echo $rate1." * ".$amount1." = ".($rate1*$amount1);
// second calculation with floats converted from strings
echo "<br><br>This should be correct as well:<br><br>";
echo $rate2." * ".$amount2." = ".($rate2*$amount2);
// set locale to Dutch to show misbehaviour
// first calculation with floats
setlocale (LC_ALL, 'nl_NL');
echo "<br><br>This should still be correct:<br><br>";
echo $rate1." * ".$amount1." = ".($rate1*$amount1);
// second calculation with floats converted from strings
echo "<br><br>This should be wrong:<br><br>";
echo $rate2." * ".$amount2." = ".($rate2*$amount2);
?>
Hope this shows the 'bug' correctly!

This is dangerous indeed. We've had already reports about this (forgot
#, or did it even only came up on php-dev@?).
Though It may sound trivial, please provide a short self-contained
script showing the (mis-)behaviour.
Marking as critical for now.

If I set my locale to Dutch in my php-script that converts currencies
for a Dutch site, I noticed that also the internal representation of
floats change as well. In Europe an amount of tenthousand dollars is
written as follows: $10.000,00 unlike the USA $10,000.00
So if I set the locale to "nl_NL" the internal representation of a
float with a point to seperate the integer part from the decimals (for
example: $amount = 68.123) is changed to a representation of a comma
','. I would like to see it changed because it messes up calculations
and the different locale settings should (IMHO) apply only to output
function and such.
Thanks,
Jonathan
