Calculating powers of integers

Question

Is there any other way in Java to calculate a power of an integer?

I use Math.pow(a, b) now, but it returns a double, and that is usually a

Answer 1

No, there is not something as short as a**b

Here is a simple loop, if you want to avoid doubles:

long result = 1;
for (int i = 1; i <= b; i++) {
   result *= a;
}

If you want to use pow and convert the result in to integer, cast the result as follows:

int result = (int)Math.pow(a, b);
