If I store '7' or '7.0' (both quoted) in d, I'd expect to get 7/2 for r when this expression is evaluated. If I store 7.0, I'd expect to get 3.5 and not 7/2. I'm not sure what I'd expect if 7 (without the quotes) was stored in d. My point is that real numbers or numbers in standard form are generally not intended to be exact. Unless they are deliberately quoted they should stay approximate, even if they appear inside a quoted expression. If this is what you intend your idea seems excellent. Nigel (UK)
