Binary/Hexadecimal floating point

How in a macro can one distinguish between binary and hexadecimal
floating point? The type attribute returns the same value for both EB
and EH and so does the length attribute. How can a macro tell the
difference?

TIA. Pierre.

Pierre,
There doesn't appear to be a direct method for doing this. However, I notice
that the scaling attribute S' is always zero for binary floating point
constants. So, as long as you specify a non-zero scale modifier on your hex
fp constants, you can do it. Yuck, it's horrible. Try to rethink what you
want to achieve.
