Hi all,
I have recently been trying out various functions in masked array module of
numpy. I have got confused at a places in the *core.py *of *ma *module.
1. In the *masked_equal *method, the docstring doesn't suggest that
the *fill_value
*gets updated by the *value *parameter of the function,
Guys,
sorry for the incomplete message,
*_DomainedBinaryOperation *for divide remainder
Related to issue 5354, where the docstring for _*MaskedBinaryOperation *says
that invalid values are pre-masked*, but for **_DomainedBinaryOperation *where
the invalid values are masked in result, even if
Wow, thanks for pointing these out! I have been using masked arrays for
quite a while now, but I never noticed these before!
Cheers!

Hi Ralf,
Thanks for the quick response! I will submit a PR soon. I noticed
What do you mean that the mean function doesn't take care of the case where
the array is empty? In the example you provided, they both end up being
NaN, which is exactly correct.

Where does it say that operations on masked arrays should not produce NaNs?
Operations on masked arrays should ignore masked data. If I have NaNs in my
masked array, but are not masked out for some reason, I expect it to give
me NaNs. The mask is not the same as NaNs. Having np.mean([]) return the

Masked arrays were invented with the specific goal to avoid carrying NaNs
in computations. Back in the days, NaNs were not available on some

I was just referring to the exception raised in the case where the length
of the array is zero. I have not thought if the example provided by
@Alexander.
I was also wondering if the automatic masking of NaN should be done or not,
which is why I asked about the difference in the operating named
exception? Did you mean warning? If warning, I recall some discussion
recently to figure out a way to hide that, but only for masked values (I
would want to see the warning if I do bad calculations in the unmasked
portions of my array).
Now I see your point 3 much more clearly. I had never

Maniteja,
Careful with advertising that you are reading up on any under-maintained
codebases. I did that for mplot3d four years ago and the previous
maintainer said tag! you're it!
I haven't been able to tag anyone since then...
Cheers!
