Reading and writing binary data

This recipe describes how to write and read any type in the binary form.

How to do it...

1. Open the console and create the folder chapter05/recipe07.
2. Navigate to the directory.
3. Create the rwbinary.go file with the following content:

        package main

        import (
          "bytes"
          "encoding/binary"
          "fmt"
        )

        func main() {
          // Writing binary values
          buf := bytes.NewBuffer([]byte{})
          if err := binary.Write(buf, binary.BigEndian, 1.004); 
          err != nil {
            panic(err)
          }
          if err := binary.Write(buf, binary.BigEndian,
                   []byte("Hello")); err != nil {
