希望这有帮助！ Hi Noel,
Yes you are correct, for instance in a code I posted earlier today:
(defun c:tanx (/ ans ang ang2) (initget "Deg Rad") (setq ans (getkword "\nInput in Degrees or Radians? : ")) (setq ang (getreal "Specify Angle: ")) (if (= ans "Deg") (setq ang (dtr ang)) ) (setq ang2 (/ (sin ang) (cos ang))) (alert (rtos ang2)) (princ)) ; end tanx (defun dtr (a) (* pi (/ a 180.0))) ; end dtr
Hope this helps!
