[Numpy-discussion] c++ code

Here is my c++ code if you want to play with it.

You'll need to find constrained_value for boost (or I can provide it as a 
patch if you request).

As for semantics, different people actually want/expect different behavior.  
I chose the 'pythonic' approach.  If you do fpa @ fpb, where fpa,b are fixed 
point numbers of same/different sizes and @ is a binary op, my library will 
_not_ promote the output.  Explicit is better.  If you want a(32 bit) x b(32 
bit) -> c(64 bit), you promote the operands explicitly first.
