I've created an array of strings using something like....

stringarray=self.karray.astype("|S8")

If the array value is a Nan I get "1.#QNAN" in my string array.

For cosmetic reasons I'd like to change this to something else, e.g.
"invalid" or "inactive".

My string array can be up to 100,000+ values.

Is there a fast way to do this?

I think this is a bug. Making the printing of nans uniform was one of the goals of numpy 1.3, although a few bits were unfixable. However, this looks fixable. If you are using 1.3 please open a ticket and note the OS and numpy version.
