I have the beginning of a fixed-pt binary lib. Fixed-pt is popular in DSP applications. It is integer arithmetic, but keeping track of the binary pt.
It is built on top of constrained_value.
It is small, so I include it here: I think you should return self& instead of self from most of the operators.
Yes, thanks (oversight)
Be sure to check the size of your type with your compiler. Some embedded and DSP compilers in the past made types that derive from operators larger. Although I think that was partially due to a operators bug that was fixed a long time ago. There have been several fixed-point libraries discussed on this list you should search the archives including one very interesting one built on proto by Maurizio Vitale IIRC. Thanks, Michael Marcin
