Wrong rounding_mode with locale "fr"

[tasiot]

Hi,

I don't know if it's really a bug or something else, but when I use the format_currency filter, the wrong rounding_mode is applied.

{{ app.request.locale }} {{ '36.625000'|format_currency('EUR') }} {{ '36.625000'|format_currency('EUR', {rounding_mode:'halfup'} }}

Results:

fr 36,62 € 36,63 €

In France, the rounding rule is halfup.

My PHP server returns "en_US_POSIX" when I run echo locale_get_default(); but the request must select the current user locale right?
