uint64le

Encode / decode little endian unsigned 64 bit integers

npm install uint64le

Usage

const uint64le = require('uint64le')

const buf = uint64le.encode(42) // returns a 8 byte buffer with 42 encoded
console.log(uint64le.decode(buf)) // returns 42

Notice

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.

API

buffer = uint64le.encode(num, [buffer], [offset])

Encode a number as a little 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 = uint64le.decode(buffer, [offset])

Decode a number from a buffer.

length = uint64le.encodingLength(num)

Always returns 8. Added to comply with the standard encoding interface in node. Similarly uint64le.encode.bytes and uint64le.decode.bytes is also set to 8.
