The format of such an integer, which may be preceded where appropriate by a sign (not in fractional parts), is:
<radix>R<appropriate_digits>Radix is the number specifying the base to be used and must be one of 2, 4, 8 or 16.
The digits which may be used will depend on the choice of base, as follows:
2 -> 0,1 4 -> 0,1,2,3 8 -> 0,1,2,3,4,5,6,7 16 -> 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,FExamples of this form for simple integers are:
