Is "is_infinity" the opposite of "is_finite" or the same as "is_plus_infinity"? The former, I would presume, but the name suggests the latter. This is the ambiguity I mentioned before. The function would be better named "is_infinite", IMO.
Agreed.
A few people have mentioned:
is_plus_infinity() is_minus_infinity() I think positive/negative is better than plus/minus. It's slightly longer but fits the terminology I understand as being more "correct". std::plus and std::minus also give a precedent for plus/minus being operations (addition and subtraction), not classifications for values.
So I'd vote for these instead: is_positive_infinity() is_negative_infinity()

Agree. Then we have: template<class T> bool is_finite(T t); template<class T> bool is_normal(T t); template<class T> bool is_subnormal(T t); template<class T> bool is_infinite(T t); template<class T> bool is_positive_infinity(T t); template<class T> bool is_negative_infinity(T t); template<class T> bool is_nan(T t); template<class T> bool is_quiet_nan(T t); template<class T> bool is_signalling_nan(T t); --Johan Råde
