Good point. Now, which of these three sets is best (or at
least preferred), and why?
1)
(define mm 1)
(define cm (* 10 mm))
(define in (* 254/10 mm))
(define pt (* 100/7227 in))
2)
mm = #1
cm = #(* 10 mm)
in = #(* 254/10 mm)
pt = #(* 100/7227 in)
3)
mm = #1
cm = 10\mm
in = 254/10\mm
pt = 100/7227\mm
Thanks.
