strconv.ErrRange Variable

The ErrRange variable is an inbuilt variable of the strconv package which indicates that a value is out of range for the target type. The value of the ErrRange variable is "value out of range".

Syntax:

*errors.errorString strconv.ErrRange

var ErrRange = errors.New("value out of range")

Parameter(s):

• None

Return Value:

The return type of strconv.ErrRange variable is a *errors.errorString, it returns the string "value out of range".

Example 1:

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

package main

import (
	"fmt"
	"strconv"
)

func main() {
	fmt.Printf("Type of strconv.ErrRange is %T\n", strconv.ErrRange)
	fmt.Println("Value of strconv.ErrRange:", strconv.ErrRange)
}

Output:

Type of strconv.ErrRange is *errors.errorString
Value of strconv.ErrRange: value out of range

Explanation:

In the above program, we imported the strconv package to use the strconv.ErrRange variable, then printed the type and value of the strconv.ErrRange variable.

Example 2:

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

package main

import (
	"fmt"
	"strconv"
)

func main() {
	result, err := strconv.ParseInt("18446744073729762559", 10, 64)
	if err != nil {
		if numErr, ok := err.(*strconv.NumError); ok {
			if numErr.Err == strconv.ErrRange {
				fmt.Println("Error:", numErr.Num, "as a", strconv.ErrRange)
				return
			}
		}
		fmt.Println(err)
		return
	}
	fmt.Println(result)
}

Output:

Error: 18446744073729762559 as a value out of range
