Type a number and read it back in words. Number mode spells decimals digit by digit (1,234.56 → “one thousand two hundred thirty-four point five six”); currency mode writes it the way a check does (“one thousand two hundred thirty-four dollars and fifty-six cents”), rounding fractions to whole cents.
Common uses
- Write the amount line on a check correctly
- Spell out figures in contracts and legal documents
- Read large numbers aloud without miscounting the zeros
