Re: [boost] [Math/nextafter] A question of naming functions...

Ooh,  the return type is an integer that is always representable as a FPT (same as the arguments) and in addition, having FPT allows infinity and NaN if one (both) of the args are infinite or NaN.  Nifty...

I do hope all these get documented somehow besides the "number of gaps" basic return value.  Thanks!

Would adding an underscore be nicer:

FPT float_distance(FPT lhs, FPT rhs);

And to be clear, this (and the other next functions) *only* apply to floating-point types.  (not integer, not decimal, not interval,
or any other type)?

next_distance() is another possible that does not explicitly limit to floating point.
