     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─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.
 
     If the current default radix, specified by the .RADIX directive,
     is 10 or less, B and D are treated as radix overrides. B and D are
     treated as hexadecimal digits if the default radix is above 11 or
     above 13, respectively.
 
     Floating-point constants may be used as initializers only with the
     REAL4, REAL8, REAL10, DWORD, QWORD, and TBYTE directives. Floating-
     point constants can be represented with an optional exponent or a
     decimal point.
