Type casting is a way to convert a variable from one data type to another data type. For example, if you want to store a long value into a simple integer then you can type cast long to int. You can convert values from one type to another using the cast operator. Its syntax is as follows −

type_name(expression)

Example

Consider the following example where the cast operator causes the division of one integer variable by another to be performed as a floating number operation.

package main

import "fmt"

func main() {

   var sum int = 17

   var count int = 5

   var mean float32

   mean = float32(sum)/float32(count)

   fmt.Printf("Value of mean : %f\n",mean)

}

When the above code is compiled and executed, it produces the following result −

Value of mean : 3.400000
