Summary: Bug in Calctool


	I think I've found a bug in calctool, as posted to the net a little
while back.  If you take the square root of a negative number, you get
"NaN" (Not a Number; should really be NaRN :-)).  On the other hand, if you
try to divide by zero, you get "Error".  Seems to me you should either get
"NaN" or "Error" both time.  What do you math types think?

	BTW, taking the square root of a negative number isn't easy, since
there isn't and +/- key.  Have to do "0 - 1 srt".  This minor problem
notwithstanding, I think calctool is pretty nifty and have put it in my
root menu.
