Formatting Numbers

Since ICU 60, the recommended mechanism for formatting numbers is NumberFormatter (Java). NumberFormatter supports the formatting of:

• Decimal Formatting
• Currencies
• Measurement Units
• Percentages
• Scientific Notation
• Compact Notation

For number ranges, including currency and measurement unit ranges, see NumberRangeFormatter (Java).

For rule-based number formatting, including spellout rules and support for traditional numbering systems not covered by base-10 decimal digits, see rbnf.md.

For the classic NumberFormat class, which also includes legacy parsing support for localized number strings, see legacy-numberformat.md.
