[Numpy-discussion] checking array for NaN values.

Is there an easy way to check an array for NaN values?  'all(array)' regards NaN as true (because it's not 0).  I've tried all(array != nan) which didn't work either.  When i call locations which i know are NaN, it returns -1.#IND.  But if i try to call all(array != -1.#IND), python interprets the # as the start of a comment.

Any thoughts?

thanks,
alex.
