Type conversion 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 : %fn",mean) }
When the above code is compiled and executed, it produces the following result −
Value of mean : 3.400000
