func main() {
	fmt.Printf("Type of strconv.ErrSyntax is %T\n", strconv.ErrSyntax)

Example 2

// Golang program to demonstrate the
// example of strconv.ErrSyntax Variable

package main

import (
	"errors"
	"fmt"
	"os"
	"strconv"
)

func main() {
	b := "123@okay"

	a, err := strconv.Atoi(b)

	if errors.Is(err, strconv.ErrSyntax) {
		fmt.Println("Error Detected:", strconv.ErrSyntax)
		os.Exit(1)
