Morton Order

[adishavit]

Is there a way to compare which of two floats/doubles lies further along the Morton curse?
Is there a direct way to do this besides rescaling, converting to integer and doing the conversion?
Something like Moore's Hilbert code function hilbert_ieee_cmp() (here and here).

Will look into this!

I implemented this a long time ago. Recently I polished the code and put it on GitHub. See zorder_knn.
