Last Updated :

Go language provides inbuilt support implementation of run-time reflection and allowing a program to manipulate objects with arbitrary types with the help of reflect package. The reflect.Int() Function in Golang is used to get the v’s underlying value, as an int64. To access this function, one needs to imports the reflect package in the program.
Syntax:
func (v Value) Int() int64
Parameters: This function does not accept any parameter.
Return Value: This function returns the v’s underlying value, as an int64.
Below examples illustrate the use of the above method in Golang:
Example 1:
package main
import (
"fmt"
"reflect"
)
func main() {
fmt.Println(reflect.ValueOf(678).Int())
}
|
Output:
678
Example 2:
package main
import (
"fmt"
"reflect"
)
const a = 2
const b = 3
func main() {
fmt.Println("Number a : ", a)
fmt.Println("Number b : ", b)
c := a + b
fmt.Println(reflect.ValueOf(c).Int())
}
|
Output:
Number a : 2
Number b : 3
