[Numpy-discussion] what is nan_to_num() for float32 ?

[Sebastian H. <ha...@ms...>]

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,
