[Numpy-discussion] Revert the return of a single NaN for `np.unique` with floating point numbers?

Hi all, In NumPy 1.21, the output of `np.unique` changed in the presence of multiple NaNs. Previously, all NaNs were returned when we now only return one (all NaNs were considered unique): a = np.array([1, 1, np.nan, np.nan, np.nan]) Before 1.21: >>> np.unique(a) array([ 1., nan, n

[Numpy-discussion] Plan for a new Indexing how-to document

Hi, all! I'm planning to write a how-to doc for ndarray indexing as per discussion in https://github.com/numpy/numpy/pull/19407. I have opened a discussion issue (https://github.com/numpy/numpy/issues/19586) with a few ideas and would love to know your opinions on them and other use-cases you'd lik
