It's a babylonian method. when i give input 36 or 25 it shows 6 or 5 as output. Like a normal square root formula. But how it works? If anybody know about babylonian method please help me to understand this code.

{
float x = num;

float y = 1;

double e = 0.000001;

while (x - y > e) {

x = (x + y) / 2;

y = num / x;
}
return x;
}
