Actually, Daniel you don't have to *think*, you've to demonstrate that it works or that it doesn't /tertium non datur/. > In your example, 1:09 represents 1/9th in calc's fraction mode, > not 1+9/60 which it would have to in order to compute with it. Not with GNU/Emacs 23.3 calc. If you bill 50 per 1 hour, you bill (/ 50 60.0 ) is 0.83 per minute. If you bill 1 hour + 9 minutes it is 69 minutes (* 0.83 69) 57.269999999999996 = 57.27 isn't it ? And the fifth column in my table (see below) does compute 57.27 or not? You may say: "Ah but this is only one example, you've been lucky!" I reply, what about the second line? (* (+ 120 48) 0.83) = 139.44 Calc is *really* smart, isn't it? cheers, Giovanni > > Regards, > > At Thu, 21 Jul 2011 13:07:28 +0200, > Giovanni Ridolfi wrote: >> >> Daniel E.
