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 Why does the same number look different in two formats?

Because there's no global standard for which punctuation goes where. Most of continental Europe uses a comma as the decimal separator and a dot (or space) as the thousands separator, while the UK, US, Ireland, Switzerland (mostly) and most former British colonies do the opposite. So €1.234,56 and €1,234.56 are the same value written two ways — only the punctuation differs. A German reader and an American reader would read the same string as completely different numbers.

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 number format will I get?

nouz picks the format from your currency, automatically. EUR, PLN, NOK, SEK, DKK and CHF all default to the European format (1.234,56), while GBP and USD default to the British/American format (1,234.56). You don't need to think about decimal or thousands separators at all — as long as your currency is set correctly on your business profile, the matching format follows for every monetary value across the app.

03 Can I override the number format?

There's no separate format setting today — the currency choice is the format choice. If you want US-style formatting on EUR (uncommon, but it happens for Swiss accountants), the workaround is to set your currency to USD temporarily. We may add an explicit override later. If you genuinely need a non-default format for your currency, email support@nouz.co and explain the situation — if multiple owners ask, we'll add it.
