No, that’s an absolutely natural extension.
What’s so special about things that have a
CD of 1?

Since, AFAIK, GCD was originally defined in the context of whole numbers,
you probably get what you deserve using it with non-integers.

It is odd, though, that even with comparison tolerance set to zero, +.

0.0000000000000036
    0j16":,.+./|.4.57 4.34 4.44
0.0000000000290870

It is commutative though:
    (-:|:)+./@>{;~4.57 4.34 4.44
1
    0j16":+./@>{;~4.57 4.34 4.44

0.0099999999999758 0.0200000000000466 4.4400000000000004

I'm not quite sure what's going on here... maybe a built in epsilon
which is independent of comparison tolerance?

Thanks,

In case you are willing to accept labelling it a problem.

As I mentioned by altering the thread’s subject, yes,
this ain’t a bug. But there may be an opportunity for
improvement without sacrifice. Or so do I think.

As Devon and Henry suggest, it's the usual problem with "exact"
representation of reals.

NB. this was not the correct answer.  A bug?

     +./x:4.57 4.34 4.44

NB. this was a work-around
Thanks!
