Re: What does ^ do in java?

I found one, as BigInteger.pow(int exponent)

Floating point arithmetic is both slower and less accurate than integer arithmetic.
(While double precision would suffice for (32-bit) integers, you lose precision if you want to work with long (64-bit) integers.)

Math.pow(double a, double b) is the power operation in Java (It returns a raised to the power of b).
