Actually, Daniel you don't have to *think*, you've to demonstrate 
that it works or that it doesn't /tertium non datur/.

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
