    Re: Russian formula for Casio
    From: Alexandre Eremenko

    I don't understand this whole business of negative number conversion:-)
    We are talking about a non-programmable calculator:
    why would one want to convert negative numbers on it??
    Enter the positive number, it will convert it, then
    if necessary switch sign.
    
    (Actually my Cassio does not permit entering negative numbers,
    strictly speaking. To enter -1, for example, you have to enter 1,
    and then press the sign change key).
    
    Alex.
