Hi !
I have a nice ndarray image viewer built on OpenGL - one annoyance though is
that is crashes if the array contains any NaN, or inf, ...
So, I found N.nan_to_num - but OpenGL (read: video cards) supports only
single precision float (N.float32)
So I get this:
>>> N.nan_to_num([N.inf])
[ 1.79769313e+308]
>>> N.nan_to_num([N.inf]).astype(N.float32)
[ inf]
Could nan_to_num() get an optional dtype argument ?
Thanks,
Sebastian Haase
