I think we should guarantee some properties: 1. The result of hypot(x, y, z, ...) shouldn't depend on the order of arguments. 2. It should be monotonic for all arguments: hypot(..., x, ...) <= hypot(..., y, ...) for abs(x) < abs(y). 3. hypot(..., inf, ...) = inf 4. hypot(..., nan, ...) = nan (if no infinities) 5. hypot(x, x, x, x) == 2*abs(x)

I think we should guarantee some properties:

1. The result of hypot(x, y, z, ...) shouldn't depend on the order of arguments.

2. It should be monotonic for all arguments: hypot(..., x, ...) <= hypot(..., y, ...) for abs(x) < abs(y).

3. hypot(..., inf, ...) = inf

4. hypot(..., nan, ...) = nan (if no infinities)

5. hypot(x, x, x, x) == 2*abs(x)
