// double Math.pow(double base, double exponent)
double twoCubed = Math.pow(2, 3); 
System.out.println("Two raised to third power: " + twoCubed); // 8.0

java to the power of

// this means 2 to the power of 4 - 2^4 - which will return 16
Math.pow(2, 4);

java math power

Method:  Let x =  2   * (1+f)
      1. Compute and return log2(x) in two pieces:
              log2(x) = w1 + w2,
         where w1 has 53-24 = 29 bit trailing zeros.
      2. Perform y*log2(x) = n+y' by simulating muti-precision
         arithmetic, where |y'|<=0.5.
      3. Return x**y = 2**n*exp(y'*log2)
