int53

serialization of 53-bit integers to and from 8 byte buffers.

usage

``js
var int53 = require('int53')

var a = Buffer(8)

int53.writeUInt64BE(0xFFFFFFFFFFF, a)

var b = Buffer('0000FFFFFFFFFFFF', 'hex')

var x = int53.readUInt64BE(b)
`

API

`js
var number = int53.readInt64BE(buffer, offset)
var number = int53.readInt64LE(buffer, offset)
var number = int53.readUInt64BE(buffer, offset)
var number = int53.readUInt64LE(buffer, offset)

int53.writeInt64BE(number, buffer, offset)
int53.writeInt64LE(number, buffer, offset)
int53.writeUInt64BE(number, buffer, offset)
int53.writeUInt64LE(number, buffer, offset)
``

why?

Sometimes you need to read and write 64-bit integers. For some
things like timestamps, file sizes, and counters the 53-bits
offered by a double is enough to get by, and easier to work with
than a bigint module.
