Tanzania formatting implementation notes

For Tanzania, format numbers with the explicit locale sw-TZ; the reference value 1234567.89 renders as 1,234,567.89.

Tanzania's reference format uses "." as the decimal mark and comma (",") for grouping. The integer uses repeating groups of three digits. Pass "sw-TZ" directly to Intl.NumberFormat instead of replacing punctuation in a preformatted string.

TZS is shown with TSh immediately before the amount; the same reference value renders as TSh1,234,567.89. 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.

Western 0–9 digits are the page's reference digit system, and the negative pattern is -n. This country is multilingual in software contexts: also test en-TZ, because language selection can change spacing, punctuation, and currency display without changing the region. Validate output with formatToParts() when spacing, signs, or bidirectional literals affect the interface.

  • Locale: sw-TZ
  • Decimal and grouping: 1,234,567.89
  • Currency: TZS → TSh1,234,567.89
  • Digits: Western 0–9 digits
