To indicate the radix of a constant, place the specifier at the end of
the number. Specifiers and hexadecimal digits can be uppercase or
lowercase. Hexadecimal numbers must always start with a decimal digit (0
to 9). If the first digit is one of the letters A to F, prefix the
number with a leading 0 to distinguish it from a symbolic name.
