And applications, like formulas and math functions. This - (defun distance-point (min max) (+ min (/ (- max min) 2.0)) ) - or special, fun things. This even has the name arithmetic in it. Well, almost. (defun arith-sum (n) (cl-loop with sum = 0 for i from 1 to (1- n) do (cl-incf sum i) finally return sum) ) (Hm - there are many ways to solve that, and this is fine by all means.) You can also compare Emacs arithmetic capabilities with what you find in a book. Do we have everything? Or do we want more? That is where it begins. -- underground experts united https://dataswamp.org/~incal
