As explained, otherwise it'll be integer
division. But I think that qualifies as a hack
(not an ugly hack tho) so there is no shame in
spotting it an "error" :)

I always just use an online calculator, like:,50&RZ=12,13,15,17,19,21,23,25&UF=2150&TF=90&SL=2.6&UN=KMH

Let's agree there is no need to do it in Lisp.
Only a desire :)

Why make things complicated? I do such stuff with spreadsheets. That's what they were invented for. Part of every office software including free ones.
