hashCode of a double is very trivial

[filiph]

Not sure if this is intended but calling number.hashCode is equivalent to number.toInt().

class _Double extends _Num implements double {
  // ...

  int get _identityHashCode {
    if (isNaN || isInfinite) return 0;
    return toInt();
  }
}

This of course means that 3.14, 3.14159 and 3.9 all have the same hashCode. It gets even more confusing when you're trying to do hashCodes of numbers that are close to zero because 0 suggests some kind of other problem.

It would be useful to have something like Java's Double.hashCode().
