Encode / decode big endian unsigned 64 bit integers
npm install uint64beEncode / decode big endian unsigned 64 bit integers
``
npm install uint64be
` js
var uint64be = require('uint64be')
var buf = uint64be.encode(42) // returns a 8 byte buffer with 42 encoded
console.log(uint64be.decode(buf)) // returns 42
`
Javascript (currently) only supports integers up to 2^53 - 1 without any
loss of precision so beware of this if you encode / decode any integers larger than that.
#### buffer = uint64be.encode(num, [buffer], [offset])
Encode a number as a big endian 64 bit unsigned integer.
Optionally you can pass a buffer + offset as the 2nd and 3rd argument
and the number will be encoded into that buffer at the given offset.
#### num = uint64be.decode(buffer, [offset])
Decode a number from a buffer.
#### length = uint64be.encodingLength(num)
Always returns 8. Added to comply with the standard encoding interface in node.uint64be.encode.bytes
Similarly and uint64be.decode.bytes is also set to 8`.
