Find the nth Power of a given number

private double Power(double a, double n) 
{
      double mult = 1;
      for(int i = 1; i <= n; i++)
      {
          mult = mult * a;
      }
      
      return mult;
}

How it works:

mult=1, i = 1
n = 5, a = 2
mult = 1 * 2 = 2

mult=2, i=2
n=5, a=2
mult=2 * 2 = 4

and so on..
