wrong algebra result

Hi,

I dont understand what happen.

I hae two script identical
When the same size of operation

One give wrong result the over fail ?

Here is the sample :

$prixfr
: string = 30
$code='FRF';
$currency_rates[$code]
: string = 6.55957
$prixfr*$currency_rates[$code]

gives me 180 , bad

and in the over it works gives me 196...

I remark via dbg debuggeur that in case
1string1string -> 1double
and in the over
1string1string -> 1integer
with same values at base

I dont know how to correct that

needs Help!

Thanks

I have tried this:
<?php
$prixfr = "30 ";
$currency_rates = "6,55957" ;
$res=$prixfr*$currency_rates;
echo ("$res");
?>
Result: 180

<?php
$prixfr = "30 ";
$currency_rates = "6.55957" ;
$res=$prixfr*$currency_rates;
echo ("$res");
?>
Result:196.7871

I think your problem is the number format: . or , ??

that's not that :

when I force $currency_rates[$code]
to be double
it doesnt give 6.55 ... but 6

I make a :

settype($prixfr, "double");
settype($currency_rates[$code], "double");

a+.
Thanks

I found an index (ist his the correct word in english ? my babylon give this ?)
When I m changing some gloabl value, algebra
errors apperas :

30*6.5 -> 396
$rdf_lang = "sp-pa";
setlocale('LC_ALL','spanish');

30*6 -> 180

I m french and doing a spanish site with no knowledge of spanish seems hard.

hey hey.

I found the correct value for spanish in spain
setlocale('LC_ALL','ES_es');

Thanks.
