I think there is also a gotcha there as you get a ratio in Common Lisp and not a floating point number. > (print (format t "1 divided by 2 is ~a and its type is ~a" (/ 1 2) (type-of (/ 1 2)))) > 1 divided by 2 is 1/2 and its type is RATIO I don't think there is a simple solution. Numbers are harder than they seem and you just need to know what happens in the particular language you are programming in.
