Square root is easy, it's the number to the power of 0.5

I'm working on writing a few plugs for System.Math, i'll try working on it.

int sqrt2(int x)
{
for (double y = 1, y2 = 2; y <= x; y++, y2++)
{
if (y * y == x)
{
return y;
}
else if (y * y < x && y2 * y2 > x)
{
int y1 = y;
int y3 = y2;
int n = 0, m = 0;
for (; y * y < x; y += 0.1, n++){;}
for (; y2 * y2 > x; y2 -= 0.1, m++){;}
if (n < m) return y1;
else return y3;
}
}
return 0;
}
if u use this method it gives sqrt for an int and it also rounds so if the accual sqrt is 9.8 it will return 10 and if its 4.2 it returns 4

Best to have a look at some existing ones however:

Sqrt can be done quickly on hardware - so you would have to write it in ASM look for an ASM plug)
Sqrt could be implemented in software if you look up a suitable algorithm.

could u not just tell me how while were waiting for a manuel

yes please. :) We also have plans for a plug scanner, tool, and generator... but Im still focused on MS5 right now...

We could really use a guide on how to do this. I'll consider writing one later unless someone else wants to.
