Constrain Within Circle?

I haven't worked all the geometry functions available yet ;)
don't know the arcade engine

but here's a good source:

http://www.2dcurves.com/conicsection/conicsectionc.html

that's the place for curves ;)

other wise wolfram's reference is absolutely great.

but coming to thing of it, my pie control must do something like 
that...

http://www.monsieurx.com/modules.php?name=News&file=article&sid=162

there's a setting button to offset the fields in and out of the 
center of the pie chart. That's the one you are looking for...

the pseudo script would say

r = radius of circle
xy = center of circle or arc
xyR[1..4] are the polygon's rects,

for each item I in xyR 
  if distance xy -> I > r
  you're out of the circle...

cheers
Xavier
