#### Declaration

    #define g_ascii_isdigit (
      c
    )

#### Description

Determines whether a character is digit (0-9).

Unlike the standard C library `isdigit()` function, this takes a `char`, not an `int`, so don’t call it on `EOF`, but no need to cast to `guchar` before passing a possibly non-ASCII character in.

#### Parameters

`c`

  Type: `-`

  Any character.
