As an aside, these would seem to belong in the double interface and not here in
the parent interface.

As I understand it, this is a problem of num being used for double/int mixed
usage in dart->JS systems, and isNaN is needed. isNaN correctly returns false
for integers.

   bool isNegative();
   bool isInfinite();
