Today, I will show you how do I convert a interface to int in golang, as above mentioned I’m going to use interface.(int) method.

Let’s start our Golang convert interface to int example

main.go

package main

import (
	"fmt"
)

func passInterface(v interface{}) {
	b, ok := v.(int)
	fmt.Println(ok)
	fmt.Println(b)
}

func main() {
	passInterface(8)
}
