Belarus formatting implementation notes
For Belarus, format numbers with the explicit locale be-BY; the reference value 1234567.89 renders as 1 234 567,89.
Belarus'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 "be-BY" directly to Intl.NumberFormat instead of replacing punctuation in a preformatted string.
BYN is shown with Br after the amount with a separating space; the same reference value renders as 1 234 567,89 Br. 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 be-BY 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: be-BY
- Decimal and grouping: 1 234 567,89
- Currency: BYN → 1 234 567,89 Br
- Digits: Western 0–9 digits
