Type casting, also known as type conversion, is a process in which we convert a value from one data type to another. In this tutorial, we'll learn about Type Casting in Golang.
Type Casting
Go is a statically typed language, which means that variable types are determined at compile time.
Type casting is necessary when we want to perform operations between variables of different types or when we want to assign a value of one type to a variable of another type.
Type Casting Syntax
The basic syntax of type casting in Golang is:
newTypeVariable := targetType(expression)
Example: Converting Integer to Float.
package main
import (
"fmt"
)
func main() {
var numInt int = 42
numFloat := float64(numInt)
fmt.Printf("Integer: %d, Float: %f\n", numInt, numFloat)
}
Output:
Integer: 42, Float: 42.000000
Example: Converting Integer to String.
package main
import (
"fmt"
"strconv"
)
func main() {
numInt := 42
numStr := strconv.Itoa(numInt)
fmt.Printf("Integer: %d, String: %s\n", numInt, numStr)
}
Output:
Integer: 42, String: 42
