Use the isdigit method to see if a character is a numeric digit character.
A positional numeral system uses a single symbol, a numerical digit, to represent numbers. It is frequently abbreviated to "only digit." Examples are "2" and "25." The word "digit" derives from the fact that the ten fingers (Latin: digiti) on each hand correspond to the ten symbols of the conventional base-ten numeric system, or decimal (Old Latin: decem, meaning "ten") digits.
The absolute value of the base determines the required numerical digit for a given numeral system with an integer basis. For instance, the base-10 decimal system requires ten digits (0 through 9), whereas the base-2 binary system only needs two digits (0 and 1).
