KahanSummation (Core 2.1.6 API)

```
public class KahanSummation
extends Object
```
Provides methods and elements for Kahan's algorithm for summing a set of numerical values with extended precision arithmetic. Often, when adding a large set of small values to a large value, the limited precision of computer arithmetic results in the contribution of the small values being lost. This limitation may result in a loss of valuable data if the total sum of the collected small values is large enough enough to make a meaningful contribution to the large value. Kahan's algorithm extends the precision of the computation so that the contribution of small values is preserved.
