[cfp-interest 3503] hypot(x, y) - C2Y F.10.5.4

[Damian McGuckin]

In the latest draft,  the first item of paragraph 1 says

 	hypot (x, y), hypot (y, x), and hypot (x, -y) are equivalent.

Is that complete?

If +/- is my poor attempt at an plus-or-minus-sign, is this more thorough:

 	hypot(+/- x, +/- y) = hypot(|x|, |y|) = hypot(|y|, |x|)

Thanks - Damian
