|
||
|
|
===========
|
||
|
|
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:
|
||
|
|
|
||

## 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.
