Formatting numbers

If the numbers are converted to the string, they usually need to be reasonably formatted. The formatting of a number means the number is printed with a given number, made up of digits and decimals. The representation of a value can also be chosen. A closely related problem with this, however, is the localization of number formatting. For example, some languages use comma-separated zeros.

How to do it...

1. Open the console and create the folder chapter03/recipe05.
2. Navigate to the directory.
3. Create the format.go file with the following content:

        package main

        import (
          "fmt"
        )

        var integer int64 = 32500
        var floatNum float64 = 22000.456

        func main() {

          // Common way how to print the decimal
          // number
          fmt.Printf("%d \n", integer)

          // Always show the sign
          fmt.Printf("%+d \n", integer)

          // Print in other base X -16, o-8, b -2, d - 10
          fmt.Printf("%X \n", integer...
