PowerIterator

All Known Implementing Classes:

PowerNIterator, PowerTwoNIterator, PowerTwoNMinusOneIterator, PowerTwoNPlusOneIterator
```
public interface PowerIterator
```
Iterator over the powers of a value x.
This API allows to efficiently calculate the various powers of x in a taylor series by storing intermediate results.

For example xⁿ can be calculated using one multiplication by storing the previously calculated x^n-1 and x.

getCurrentPower() will be called first to retrieve the initial value.
For later iterations calculateNextPower() will be called before getCurrentPower().
