Number has methods:

• step
• sign
• <=>
• significant
• round
• clamp

not make sense for complex

see why inheritance makes things complex?

(pun intended)

Uh, how does step not make sense in a complex setting? It is quite possible to step even in a complex space, but an implementation may want to check that the points is parallel to the line that the step defines.

significant and round makes total sense and would operate on each axis independently. All three would require complex specific implementations (that at least in significant and rounds' case would make heavy use of the base implementation.

@yxhuvud I agree that step somewhat makes sense but as you said, the method gets a lot more complex in 2d.

Please: let's discuss if we want to change the Number interface to not guarantee an ordering (I disagree on this change) in another issue, this PR can't be merged until that is agreed on.

Closing because it's stalled for bigger scoped changes to Number. The implementation is more than trivial, so not need to carry this PR around.
