Trinidad and Tobago formatting implementation notes

For Trinidad and Tobago, format numbers with the explicit locale en-TT; the reference value 1234567.89 renders as 1,234,567.89.

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

TTD is shown with TT$ immediately before the amount; the same reference value renders as TT$1,234,567.89. 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. Treat en-TT 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: en-TT
  • Decimal and grouping: 1,234,567.89
  • Currency: TTD → TT$1,234,567.89
  • Digits: Western 0–9 digits
