Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “You can test this code from ch03/type-definition/main.go.”

A block of code is set as follows:

func main() {
	a := -1
	var b uint32
	b = 4294967295
	var c float32 = 42.1
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

func main() {
    a := 4294967295
 
    b := uint32(a)
 
    c := float32(b)
}
