Russia formatting implementation notes
For Russia, format numbers with the explicit locale ru-RU; the reference value 1234567.89 renders as 1 234 567,89.
Russia's reference format uses "," as the decimal mark and a narrow non-breaking space (U+202F) for grouping. The integer uses repeating groups of three digits. Pass "ru-RU" directly to Intl.NumberFormat instead of replacing punctuation in a preformatted string.
RUB is shown with ₽ after the amount with a separating space; the same reference value renders as 1 234 567,89 ₽. The percent sign appears after the amount with a separating space. Use the ISO currency code for storage and interchange because a visible symbol can be shared by unrelated currencies.
Western 0–9 digits are the page's reference digit system, and the negative pattern is -n. Treat ru-RU as the reference locale for this page, but still respect the user's explicitly selected language and numbering-system preferences. Validate output with formatToParts() when spacing, signs, or bidirectional literals affect the interface.
- Locale: ru-RU
- Decimal and grouping: 1 234 567,89
- Currency: RUB → 1 234 567,89 ₽
- Digits: Western 0–9 digits

What's different here
- Decimal mark is a comma (,) (en-US uses a period (.)).
- Thousands are grouped with a narrow no-break space (U+202F) (en-US uses a comma (,)).
- The currency symbol goes after the amount with a space (en-US: immediately before the amount).
- The percent sign goes after the number with a space (en-US: immediately after the number).
- Uses the same number pattern (decimal mark, grouping, symbol and percent placement) as France, Belgium, Portugal, Finland, Czech Republic and Hungary in Europe, plus 2 pages in other regions.
- Nearby differences: Germany (de-DE) groups with a period (.) instead of a narrow no-break space (U+202F); Sweden (sv-SE) groups with a no-break space (U+00A0) instead of a narrow no-break space (U+202F); Norway (nb-NO) groups with a no-break space (U+00A0) instead of a narrow no-break space (U+202F); Denmark (da-DK) groups with a period (.) instead of a narrow no-break space (U+202F).
- Currency: RUB has ISO minor unit 2.
- The grouping character is a narrow no-break space (U+202F), not a regular space. Normalise it before parsing user input or comparing strings.
- Postal address order: country → region → postcode + city → suburb → street + street number → building → name. See address formats.
Code Examples
// Basic number
new Intl.NumberFormat('ru-RU').format(1234567.89)
// → "1 234 567,89"
// Currency
new Intl.NumberFormat('ru-RU', {
style: 'currency',
currency: 'RUB'
}).format(1234567.89)
// → "1 234 567,89 ₽"
// Percentage
new Intl.NumberFormat('ru-RU', {
style: 'percent',
minimumFractionDigits: 1
}).format(0.125)
// Compact notation
new Intl.NumberFormat('ru-RU', {
notation: 'compact'
}).format(1234567)Negative Number Formats
