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();
 
   num abs();
   num round();
   num floor();
   num ceil();
   num truncate();
 
   int toInt();
   double toDouble();
 
   String toStringAsFixed(int fractionDigits);
   String toStringAsExponential(int fractionDigits);
   String toStringAsPrecision(int precision);
   String toRadixString(int radix);
 }
