For an integer `n` from 0 to 15, `(digit-to-char n)` is the character corresponding to `n` in hex notation, using uppercase letters for digits exceeding 9. If `n` is in the appropriate range, that result is of course also the binary, octal, and decimal digit.

The guard for `digit-to-char` requires its argument to be an integer between 0 and 15, inclusive.
