Is there any other way in Java to calculate a power of an integer?
Math.pow(a, b) now, but it returns a
double, and that is usually a lot of work, and looks less clean when you just want to use
ints (a power will then also always result in an
Is there something as simple as
a**b like in Python?
Integers are only 32 bits. This means that its max value is
2^31 -1. As you see, for very small numbers, you quickly have a result which can’t be represented by an integer anymore. That’s why
If you want arbitrary integer precision, use
BigInteger.pow. But it’s of course less efficient.
