Here is my current run-time fixed-pt. In this version, fixed-pt bit widths are set at run-time, becuase I use this from python. It is simple to convert this to compile-time if desired.
The code is based on the boost::constrained_value
Hi, I have no doubt of the utility of a fixed point library with constraints given at run-time, but I will prefer that the interface be based on Range and Resolution (as in http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3352.htm) instead of in IntegerBits and FractionalBits. I need sometimes to have fixed points that have less bits than fractional bits and give negative numbers for IntegerBits or FractionalBits seems to me counterintuitive. Of course this is just a point of view and conversion between the different formats could be provided by the library. Best, Vicente
