math.sqrt Questions

Are there any alternatives to using Math.sqrt() to get the square root of an unknown value?
For example:
var random = (Math.random() * (999 - 1)) + 1;
var sqrt = Math.sqrt(random);
I've heard t...

How can I find the complexity of this function?
private double EuclideanDistance(MFCC.MFCCFrame vec1, MFCC.MFCCFrame vec2)
{
double Distance = 0.0;
for (int K = 0; K < 13; K++)
Distance += (...

We have a test exercise where you need to find out whether a given N number is a square of another number or no, with the smallest time complexity.

public static boolean what2(int n) {

I would like to understand why something is happening. I needed to implement the integer square root in Python (isqrt(64) = 8 = isqrt(80)). I was convinced that the naive approach:
def isqrt(n):

I'm trying to implement Fast Inverse Square Root on java in order to speed up vector normalization. However, when I implement the single-precision version in Java, I get speeds about the same as 1F...

I know that Math.sqrt calls StrictMath.sqrt(double a).
Method signature in StrictMath class:
public static native double sqrt(double a);

I was looking over this code to calculate math.sqrt in Java. Why did they use hex values in some of the loops and normal values for variables? What benefits are there to use hex?
