two-product =========== Computes the product of two floating point numbers as a 2-term nonoverlapping increasing sequence. ## Install ``` npm install two-product ``` ## Example ```javascript var twoProduct = require("two-product") console.log(twoProduct(1 + Math.pow(2, -52), Math.pow(2, 52) + 1)) ``` Output: ```javascript [ 2.220446049250313e-16, 4503599627370498 ] ``` ## API ### `require("two-product")(a, b[, result])` Multiplies `a` and `b` and returns the product as a non-overlapping sequence. `result` is an optional length 2 array that stores the result. * `a` is a number * `b` is a number * `result` is an optional length 2 array that gets the result of multiplying `a` and `b` **Returns** A length 2 array representing the product of `a` and `b` as an expansion. The first entry is the lower order bits, and the second entry is the upper order bits. **Note** This algorithm does not work correctly with denormalized numbers. ## Credits JavaScript implementation (c) 2013-2014 Mikola Lysenko.
