Hands-On Go Programming

By: Tarik Guney

Overview of this book

<p>With its C-like speed, simplicity, and power for a growing number of system-level programming domains, Go has become increasingly popular among programmers. Hands-On Go Programming teaches you the Go programming by solving commonly faced problems with the help of recipes. You will start by installing Go binaries and get familiar with the tools used for developing an application. Once you have understood these tasks, you will be able to manipulate strings and use them in built-in function constructs to create a complex value from two floating-point values. You will discover how to perform an arithmetic operation date and time, along with parsing them from string values. In addition to this, you will cover concurrency in Go, performing various web programming tasks, implementing system programming, reading and writing files, and honing many fundamental Go programming skills such as proper error handling and logging, among others. Whether you are an expert programmer or newbie, this book helps you understand how various answers are programmed in the Go language.</p>

Converting integer and float values into a string


In this section, we're going to learn how to convert integer and float values into string values. At first, this may seem a little complex, but after this section you will feel comfortable enough to work with those conversions. So let's go back to our editor and see how we can do it.

Converting an integer value into a string value

Let's start with converting an integer value into a string value:

  1. Under the string conversion package, which is strconv, we have a bunch of functions that we can use for these conversions; one of these functions is FormatInt.
  2. So let's go ahead and use base 10. You can have different bases, such as 16, 10, and 24.
  3. If you look at the signature, you'll see that it returns a string.
  4. Now, the code will not work exactly the way we want, but we're going to see why and we're going to fix it. The following output is obtained when you run the code that has been previously described:
  1. Now, we know that it accepts integer type 64;...
