Bangladesh formatting implementation notes
For Bangladesh, format numbers with the explicit locale bn-BD; the reference value 1234567.89 renders as 12,34,567.89.
Bangladesh's reference format uses "." as the decimal mark and comma (",") for grouping. The integer uses Indian 3-then-2 grouping, so digits group as lakh/crore values rather than repeating groups of three. Pass "bn-BD" directly to Intl.NumberFormat instead of replacing punctuation in a preformatted string.
BDT is shown with ৳ immediately before the amount; the same reference value renders as ৳12,34,567.89. The percent sign appears immediately after the amount. Use the ISO currency code for storage and interchange because a visible symbol can be shared by unrelated currencies.
Bengali digits are the page's reference digit system, and the negative pattern is -n. Treat bn-BD 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: bn-BD
- Decimal and grouping: 12,34,567.89
- Currency: BDT → ৳12,34,567.89
- Digits: Bengali digits

What's different here
- The integer uses Indian 3-then-2 grouping (en-US uses repeating groups of three).
- The reference digit system is Bengali digits (en-US: Western 0–9 digits).
- Uses the same number pattern (decimal mark, grouping, symbol and percent placement) as India and Pakistan.
- Nearby differences: Japan (ja-JP) uses repeating groups of three instead of Indian 3-then-2 grouping; China (zh-CN) uses repeating groups of three instead of Indian 3-then-2 grouping; Hong Kong (zh-HK) uses repeating groups of three instead of Indian 3-then-2 grouping; Taiwan (zh-TW) uses repeating groups of three instead of Indian 3-then-2 grouping.
- Currency: BDT has ISO minor unit 2.
- With 3-then-2 grouping the reference value renders as 12,34,567.89, so don't reuse a fixed "every three digits" mask.
- If an interface needs Western 0–9 digits instead of Bengali digits, request them explicitly (for example numberingSystem: "latn") rather than converting output strings.
- Postal address order: name → building → street number + street → district → city + postcode → country. See address formats.
Code Examples
// Basic number
new Intl.NumberFormat('bn-BD').format(1234567.89)
// → "12,34,567.89"
// Currency
new Intl.NumberFormat('bn-BD', {
style: 'currency',
currency: 'BDT'
}).format(1234567.89)
// → "৳12,34,567.89"
// Percentage
new Intl.NumberFormat('bn-BD', {
style: 'percent',
minimumFractionDigits: 1
}).format(0.125)
// Compact notation
new Intl.NumberFormat('bn-BD', {
notation: 'compact'
}).format(1234567)Negative Number Formats
new Intl.NumberFormat('bn-BD').format(-1234567.89)new Intl.NumberFormat('bn-BD', { style: 'currency', currency: 'BDT', currencySign: 'accounting' }).format(-1234567.89)Edge Cases & Notes
