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: * Jonathan Richard Shewchuk, ["Adaptive precision floating-point arithmetic and fast robust geometric predicates"](http://www.cs.cmu.edu/afs/cs/project/quake/public/papers/robust-arithmetic.ps). 1997 ## 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` ## Credits Based on JRS' robust geometric predicates for floating point arithmetic.
