Hi, this lib only provides methods to read data from buffer easily, and all the apis are based on nodejs's Buffer api in here.

What I believe is that packages in npm should do one thing and one thing well. For 64-bit integers, as nodes doesn't support it, so there is no standard which way we should store it, in file or in some protocols on network. Even it get read, there is no long type in js to store in in memory. Converting to double never will be an option.

So I don't think that how to translate 64-bit integer into bytes is the responsibility of this package. I highly suggest the package long in npm. you can write some very simple functions to make this package works well with long. And that's what I'm doing right now.

Thx
