>>> INF
1.#INF
>>> NA = INF - INF
>>> NA
-1.#IND
>>> equal(NA,NA)
1
>>> 

I hope I am not driving everyone crazy with this, but I get >>> equal(NA,NA)
-> 1 on windows
version of NumPy. Like most people I use windows not as much as Unix, but
this is problematic for cross platform issues. And non of the tricks we
talked
about would work for NaN.

Thanks,

Hoon,

Don't think this is problem, because works fine on my Solaris 1.4Py.
