That so, I have used the vocabulary/phrasing in my code, like
here
(defun isbn--char-to-int (c)
"Convert a char C into the integer it displays, e.g. 9 for ?9."
(- c ?0) )
does that mean I should change that into ditto number on
might wonder?

There is also the mention of "digit" all the time ... but
that's in the Emacs regexps so can't be all bad. The word
"bit" = "binary digit" BTW, not ditto "in----r" as many
people think.
But the `pi' isn't pi in Emacs anymore but `float-pi'!
(defun roll-out (chainring sprocket bsd tire)
(let*((diameter (+ bsd (* 2 tire)))
(circum (* diameter float-pi))
(roll-out (* (/ chainring sprocket 1.0) circum)) )
(list chainring sprocket roll-out) ))
;; (roll-out 34 25 622 23) ; (34 25 2854.0740906720002)

Here, BSD = Bead Seat Diameter.
