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.

For more information, see:

Install

	npm install robust-sum

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 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
