Rapaire:

With all due deference, which is precious little, I would point out that even in hex eleven thousand, a real number in decimal, is not expressed as   24 or 25,   18 or 19.

You are perhaps thinking of the binary representation, 1-1-0-0-0 which represents the real number 24, which is represented in hexadecimal as 18; but which, as you must realize, is unusual in that it has the property of having nothing to do with anything.
