JSON numbers are interpreted as float64 and not int

var x interface{}
json.Unmarshal([]byte("1"), &x)
fmt.Printf("%T", x) // "float64"

What do you mean? Could you provide some concrete examples
demonstrating what is missing in encoding/json?

Possibly @tcyrus means that JSON numbers are interpreted as float64 and not int?

var x interface{}
json.Unmarshal([]byte("1"), &x)
fmt.Printf("%T", x) // "float64"

That's because there is no int type in JSON, but number https://tools.ietf.org/html/rfc7159#page-6
