Like Roger, I'm totally confused as to what you're really trying to say here...but
Are you saying you're trying to represent the integer and fractional portion of a value as the integer value of each in two separate bit fields so that the internal storage could be
bit positions 1-15 11111100 0000000 54321098 7654321
where the decimal is an implied one????
If not, try again in complete detail to explain what it is you are trying to do...
