robust-sum
==========
Computes the sum of two increasing non-overlapping sequences of floats as an increasing non-overlapping sequence. This can be used to perform exact arithmetic calculations on floating point values.

## Install
npm install robust-sum
## Example
```javascript
var robustSum = require("robust-sum")
var seq = robustSum([1, 64], [1e-64, 1e64])
console.log("result = ", seq)
```
## API
### `require("robust-sum")(a, b)`
Computes the sum of two non-overlapping increasing sequences of floats exactly as a non-overlapping increasing sequence of floats.
* `a` is a non-overlapping sequence of floats that is increasing in magnitude
* `b` is a non-overlapping sequence of floats that is increasing magnitude
**Returns** A non-overlapping increasing sequence that encodes the result of `a+b`
