  2. Fixed Point (Chapter 13): Clarification Request

Re: Fixed Point (Chapter 13): Clarification Request

I always understood fixpoint to have an implicit denominator that was restricted to a positive (integer) power of 2 (which could be fixed, or could be configured).
Arbitrary denominators mean that multiply has to perform a subsequent divide after the operation, instead of a simple shift.
I didn't think anyone was suggesting that.

Nick,

Thank you for your response and proposed clarification.

This proposal for how to use the numbers fundamentally realigns our interpretation of how this would be used. This is much closer to the type of ADC work we've seen in the past, as opposed to do a hard "fixed point" format specification. I support the clarification. Perhaps we should see it included in the spec (merged).

Thanks,
Cohen
