Hello to all. I know this topic is not a Palm-specific one, but Palm is a
place where it applies, because of the known limitations the processor have.
So, I need to calculate the distance between two points (x1,y1) and
(x2,y2) for very much times. That is, calculating the
sqrt((x2-x1)^2+(y2-y1)^2). The problem is that, using floating point to do
this is very slow and this is time critical for me. I am interested in an
approximation which doesn't eat so much cycles and returns a quite close
result (I only need the integer square root).
Thanks in advance,
Dan Patrutiu
