I think this is the same for every other programming language. It depends on how expensive calculating the half height is and if you want to make your code possibly less readable by introducing an extra variable. If there is no real performance gain by calculating the height only once, I would recommend just to calculate the half height every time it is needed. But adding a variable could also improve your code, if your code is littered with "height / 2" statements it would be sane to just put it in a variable. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
