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.config([config]) // get/set configuration
i64.new(config) // new instance factory

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.
