Characters

The Is Digit node takes in a character literal and returns if that character is a digit. Digit characters are numbers that have a numeric value to them and are not a symbol.

Inputs

Character (char)

The character literal to check.

Outputs

* (bool)

Returns true if Character is a digit, false otherwise. Digits recognized by this node are given the delegation Nd in Unicode

An easy way to remember the difference between this node and the Is Number node is: All digits are numbers, but not all numbers are digits.

• ½, ①, 1, 2, 3 all count as numbers.
• 1, 2, 3 also count as digits.
