#intparts

Manipulate the integer parts of a JS Number, including frexp and ldexp.

##Author(s) Christoph Zurnieden czurnieden@gmx.de

##Installation

$ git clone https://github.com/czurnieden/intparts.git
$ cd intparts
$ npm install -g

There is also a Unix (or newer Macs) dependent CLI version in ./bin.

Please be aware that this module assumes little endian.

##Version

0.0.1 Initial publication

##Description

This library implements some of the functions to inspect the innards of a 64 bit double, the default type in ECMAScript up to version 5.1 at least. It allows direct manipulation of the bits in a Number. Included are ports of C-lib's frexp and ldexp.

This module runs as ams.js where applicable.

##Usage

The usage is like with any other node/browser module:

var ip = require('intparts');
var raw_exponent = ip.getexponent(123.312); // 0x405
var unbiased_exponent = ip.frexp(123.321)[1]; // 7

This program offers ten functions which are in alphabetical order:

Return: the manipulated number

Return: the manipulated number

Return: the manipulated number

This module does no error catching.
