Angles and trig

[chipanpriest]

So I've been playing around with angles and I ran into a problem. This is my code:

Turing:

View.Set ("offscreenonly") var lin1 : real var x, y, click : int var angle : real loop     mousewhere (x, y, click)     lin1 := sqrt (x ** 2 + y ** 2)     if x = 0 then         angle := 90     else         angle := arctand (y div x) %< this is the problem     end if     put "x = ", x     put "y = ", y     put "Length of line = ", lin1     put "Angle to x axis = ", angle     Draw.Line (0, 0, x, y, 7)     View.Update     cls end loop

When I put my mouse under 45 degrees, it just says it's at 0 degree. I'm not sure if this is something I'm doing wrong or if Turing is messing up.

Look up the definition of div in the Turing Help. Then, consider what happens when y = 197 and x = 300 (as in your picture).

Oh wow, thanks! I just replaced it with a "/" so it works with real numbers
