math.MaxInt8 Constant

The MaxInt8 constant is an inbuilt constant of the math package which is used to get the highest (maximum) value that can be represented by an int8.

The value of math.MaxInt8 constants is 1<<7 - 1 or 127.

Syntax

int math.MaxInt8

Parameters

• None

Return Value

The return type of math.MaxInt8 constant is int, it returns the highest (maximum) value that can be represented by an int8.

Example 1

// Golang program to demonstrate the
// example of math.MaxInt8 Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.MaxInt8 is %T\n", math.MaxInt8)
	fmt.Println("Value of math.MaxInt8:", math.MaxInt8)
}

Output:

Type of math.MaxInt8 is int
Value of math.MaxInt8: 127

Explanation:

In the above program, we imported the math package to use the math.MaxInt8 constant, then printed the type and value of the math.MaxInt8 constant.

Example 2

// Golang program to demonstrate the
// example of math.MaxInt8 Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of MaxInt8.
func getMaxInt8() int {
	return math.MaxInt8
}

func main() {
	fmt.Println("Value of math.MaxInt8:", getMaxInt8())
}

Output:

Value of math.MaxInt8: 127
