Could uarray be refactored into an object with nominal array and std array attributes?

[Log-Dog012]

Currently, uarray is an array of individual ufloat objects.

I'm wondering if it's possible to refactor uarray into a standalone object with two core attributes:

• n: an array storing all nominal values of the elements
• u: an array storing all standard deviations of the elements

This change would simplify bulk access to nominal/std values and might also improve performance for large array operations.

Just curious to hear the maintainers' and community's thoughts on this optimization direction!

@Log-Dog012 Yes, I think this would make creating and using uncertainties on array data much simpler. I think I have suggested this a few times in the past, too, but not done the work ;).

Being a breaking change, we probably want to make a different object with a new name (perhaps UNDArray? Suggestions welcome) that has n (an ndarray with dtype float64) and u (either a float scalar or an ndarray with dtype float64 that exactly matches the shape of n). That would also need all of the propagation code to be added.

So: Good idea, but some real work would be needed. I think this would be worth pursuing, but I don't see that I have the time to work on this. If you're interested in working on that, please do.
