so:
In [53]: a
Out[53]: array([ 1., 2., nan])
In [54]: b
Out[54]: array([0, 1, 2])
In [55]: a + b
Out[55]: array([ 1., 3., nan])
and nanadd(a,b) would yield:
array([ 1., 3., 2.)
I don't see how that is particularly useful, at least not any more
useful that nanprod, nandiv, etc, etc...
What am I missing?
