Use `encoding/binary`. Yes, you have to care about byte order. But that's inherent to the question. There is no canonical way in which an integer correspond to a slice of bytes, you actually have to say how to encode it. That also doesn't cause any problems - on the contrary, being explicit about that means you *don't* get into issues (for not knowing what byte order data is in).

So, you probably want to do b := make([]byte, 8) binary.BigEndian.PutUint64(b, uint64(v)) and v := int64(binary.BigEndian.Uint64(b)) On Mon, Nov 21, 2022 at 9:57 AM Nikhilesh Susarla <nikhilesh1...@gmail.com> wrote: > Hi, > > I have an int64 value say 12 > I want to convert that to []byte array. > How do we do that.
