Re: [boost] [rational] Which way should std::numeric_limits::min go?

I would treat it as a variant of the integer types, and set min() to the most negative value, and max() to the most positive value. I suppose denorm_min could be the smallest positive value, but I don't think there's any prior art for that.

The only built-in types that define denorm_min use that function to define min, that's why I was thinking of using denorm_min for min too (instead of lowest, which the built-in integers use). I'm going to use some helper templates, since I'll have to use the component type's numeric_limits, and I'll have to specialize on signed vs. unsigned, bounded vs. unbounded, etc. Daryle W.
