[removed] reading 3 bytes Buffer as an integer

Question

Let\'s say I have a hex data stream, which I want to divide into 3-bytes blocks which I need to read as an integer.

For example: given a hex string 01be638119704d4

Answer 1

you should convert three byte to four byte.

function three(var sample){
    var buffer = new Buffer(sample, 'hex');

    var buf = new Buffer(1);
    buf[0] = 0x0;

    return Buffer.concat([buf, buffer.slice(0, 3)]).readUInt32BE();
}

You can try this function.
