Square Root
 

How can I implement a decently fast square root function? Is there any inline assembly I can use?

Do you need to take the sqr of the number every loop? If you don't then just find the sqr of the particular number and define it as a constant. If you still need a fast sqr function let me know. Private message me cause I normally forget where I've posted recently lol. :D

I'm not a programmer, and I'm not sure if this applies to your question or not, but check our Question of the Day ...

If what you find there is of no help, I'll mention your post to our programming sub-team.

try this bit of code, it should give you a quick way to find square roots... but only for ints. It is accurate up to a certian point it should have enough accuracy for anything that needs to be done with our robots. If you need anything else let me know.

inline int sroot(int n)
{
int c = 0; int a = 1;
do {n -= a; a += 2; ++c;}
while (n > 0);
return c;
}
