Braille is a tactile writing system used by people who are visually impaired. Each digit is represented by a specific pattern of raised dots within a 2×3 cell. In this app, the Braille decimal system encodes digits 0–9.
Each digit is preceded by the number indicator (⠼), which signals that the following characters represent numbers rather than letters.
These correspond to: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
Braille numerals are used in Braille books, signage, and electronic Braille displays. The number sign distinguishes numeric content from alphabetic text.
