[Numpy-discussion] Boolean arrays with nulls?

[Stuart Reynolds]

Is there an efficient way to represent bool arrays with null entries?

Tools like pandas push you very hard into 64 bit float  representations -
64 bits where 3 will suffice is neither efficient for memory, nor
(consequently), speed.

What I’m hoping for is that there’s a structure that is ‘viewed’ as
nan-able float data, but backed but a more efficient structures internally.

Thanks
