EU number formatting:
comma decimal, dot thousands.

Why €1.234,56 looks right to a German owner and wrong to an American one — and how to flip it.

The example. One thousand two hundred thirty-four point five six is €1.234,56 in German format, €1,234.56 in US format. nouz picks one based on your currency.

Number formatting is one of those things you don't notice until it's wrong, and then it's suddenly all you can see. Every monetary value in nouz uses the format conventions for your chosen currency — so the question of "comma or dot for decimals" is answered automatically once you set the currency right.

01 Two formats, same number

There's no global standard for which symbol goes where. Most of continental Europe uses a comma as the decimal separator and a dot (or space) as the thousands separator. The UK, US, Ireland, Switzerland (mostly) and most former British colonies do the opposite. The number is the same; only the punctuation differs.

A German reader sees €1.234 and reads "one thousand two hundred thirty-four". An American reader sees €1.234 and reads "one point two three four" — completely different number. Same string, two readings. nouz picks the right one for your context.

02 Which format you get

nouz picks the format from your currency. EUR, PLN, NOK, SEK, DKK, CHF all default to the European format (1.234,56). GBP, USD default to the British/American format (1,234.56). The choice is automatic — you don't need to think about it as long as your currency is right.

03 How to override

There's no separate format setting — if you want US-style formatting on EUR (uncommon, but it happens for Swiss accountants), set your currency to USD temporarily. We may add an explicit override later; for now, the currency choice is the format choice.

If you genuinely need a non-default format for your currency, email support@nouz.co and explain the situation — if multiple owners ask for the same thing, we'll add the override.
