General Category - Decimal Number

Decimal Number is a classification for characters that represent digits used in decimal numbering systems, such as 0 through 9 in Western scripts or their equivalents in other languages, like Devanagari numerals. These characters are distinct from other digit types because they are specifically intended for base‑10 arithmetic, enabling numeric operations like addition and multiplication. The value also includes superscript or subscript forms of digits when they retain their numeric identity, but it excludes characters that only look like digits or are used for other purposes, such as Roman numerals or fractions, which have separate classifications. For software, this value helps identify which characters can be safely parsed as integers in a given locale, ensuring that text processing and data validation correctly interpret user‑supplied numbers across different writing systems.
