Hello,
I am not sure if the following is a bug or not. I recently tried to set the
print precision in numpy but it didn't seem to make a difference. It seems
that the use of np.ma.masked_invalid results in arrays printing precision of
12 regardless of the default setting or any subsequent setting. Generating
masked arrays does not seem to have this behaviour. Is this a bug or am I
doing it wrong?
Thanks,
Bevan
