    ebml-varint

    Encode and decode EBML variable sized integers.

    npm install ebml-varint
    

    Usage

    The interfaces exposes the two methods encode(num, [buffer], [offset]) and decode(buffer, [start], [end]) for converting a number from and to a buffer. Additionally the method encodingLength(num) returns the number of bytes required to encode a given integer, and decodingLength(buffer, [start], [end]) returns the number of bytes the integer occupies in the buffer.

    var varint = require('ebml-varint');
     
    var buffer = varint.encode(256); // Returns a buffer with two bytes [0x41, 0x00]
    var num = varint.decode(buffer); // Returns the number 256
     
    varint.encodingLength(256); // Returns two
    varint.decodingLength(buffer); // Also returns two

    Note that Javascript can only accurately represent integers up to 2^53 - 1, the encode method will throw an error if trying to encode an integer bigger than that.
