I want to ask, how to store a number (integer in JS) in buffer using buffer.writeInt16BE().

Assume I have a number such as

var a = 40000;

40000(10) = 9C40 (16)

how can I store 40000 in buffer of size of 2, so it looks something like: 

<9c, 40>

You can't use buf.writeInt16BE() because 40000 is larger than 32768. However if you use buf.writeUInt16BE() you can write 40000 to the buffer just fine.

    Those are [methods](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_readuint16be_offset_noassert) available on the Buffer instance, not global functions. – mscdex May 14 '14 at 14:38
