Currency Wrong on Language

Two language cart. English & Spanish.

English shows ok as US Dollar.

When cart is changed to Spanish it's displaying amounts as : $230,00 instead of $230.00

Only one currency is set US DOLLAR.

Is this a known bug or do I need to set something up.

This is how products also are set .... 87.000 ?

check the spanish.php in spanish files in language folder

Spanish.php doesn't have currency settings.

But the spanish language file decides the "decimal point". Many (Ass-backward) countries use decimals for commas and commas for decimals. check the catalog/language/spanish/spanish.php file for decimal_point
