Hi -
It might be faster if you had the computer find the square
root of a number by implementing an algorithim which would use the
long-hand method of square roots. That way no time would be wasted calculating
to unnecessary precision.
Of course, try replacing raising a value to a power with
simply multiplying it by itself. In my BASIC-09 manual (just to give
an example), it says that multiplying reals took about 990 clock cycles,
while raising a real to a number took 39,200 cycles! Of course Euphoria
isn't basic and it's running on a much better system, but I stil imagine
that would speed things up slightly. Side note here -- I think it would be
great if such a table existed for Euphoria. Does anyone know of such a thing?
Also, you realize if delta X and delta Y are equal than the distance is simply
sqrt(2)*(x2-x1). <-- 2D dist. equ.
It's quite possible that you have already implemented these things, but
beyond things
like these which (may) speed up the code. If you have already done these, sorry
for wasting your time,
if not, I hope this has helped. If you get any better suggestions, I'm curious
to find out how. Hope I was of some service,
