# pairwiseSum

From PreciseSums v0.3
by Matthew Fidler

##### Return an accurate floating point sum of values

This was taken by NumPy and adapted for use here. It is more accurate than a standard sum, but still has numerical issues. Its main benefit is that it is about the same amount of time as a standard time with the added accuracy.

##### Usage

`pairwiseSum(numbers)`

##### Arguments

- numbers
A vector of numbers to sum.

##### Value

A sum of numbers with a rounding error of O(lg n) instead of O(n).
