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.

Example
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 magnitudeb
is a non-overlapping sequence of floats that is increasing magnitude
Returns A non-overlapping increasing sequence that encodes the result of a+b
