Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (i64) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

i64

URL safe base64 integers and conversion tools

Install

npm install i64

Usage

var i64 = require('i64');

i64.valueOf([int64_string])       // value as Numeric Base64 String, set option
i64.isI64(int64_string)           // true if a valid int64_string is passed
i64.asInt([integer])              // get/set value as Integer
i64.asHex([hex_string])           // get/set value as Hex
i64.asDate([date])                // get/set value as Date
i64.config([config])              // get/set configuration
i64.new(config)                   // new instance factory

Numeric Base64 String Digits

As an extension of Base36 digits, Numeric Base64 String digits are:

Base64  Base10
------  -------
0..9    0 to 9
a..z    10 to 25
A..Z    26 to 61
-       62       (dash)
_       63       (underscore)

Examples

echo i64.asInt(64)                      // _      integer to base64
i64.valueOf('a'); echo i64.asInt()      // 10     base64 to integer 
i64.asHex('ff');  echo i64.asInt()      // 255    hex to integer 
i64.asDate(new Date()); echo i64.as64() // 38dc3g date to int64_string

Default Config

{ 
   // future use: part of asDate, asMicrotime and asGeo
}

Big and Fast integer handling

Large integer string conversions are handled complements of alan/clarke/int-encoder.

Normal integers are handled by a faster radix converter.

upcoming 0.3.x changes

add asDate()
add asMicrotime()
add asGeo()
asTYPE() functions will return the value as TYPE as is currently done
asTYPE(value) will change to return 'this', which will enabling chaining like:

i64.valueOf('a').asInt()
