math.MaxUint8 Constant

The MaxUint8 constant is an inbuilt constant of the math package which is used to get the highest (maximum) value that can be represented by a uint8 (unsigned int8).

The value of math.MaxUint8 constants is 1<<8 - 1 or 255.

Syntax

int math.MaxUint8

Parameters

None

Return Value

The return type of math.MaxUint8 constant is int, it returns the highest (maximum) value that can be represented by a uint8.

Example 1

// Golang program to demonstrate the
// example of math.MaxUint8 Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.MaxUint8 is %T\n", math.MaxUint8)
	fmt.Println("Value of math.MaxUint8:", math.MaxUint8)
}

Output:

Type of math.MaxUint8 is int
Value of math.MaxUint8: 255

Explanation:

In the above program, we imported the math package to use the math.MaxUint8 constant, then printed the type and value of the math.MaxUint8 constant.

Example 2

// Golang program to demonstrate the
// example of math.MaxUint8 Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of MaxUint8.
func getMaxUint8() int {
	return math.MaxUint8
}

func main() {
	fmt.Println("Value of math.MaxUint8:", getMaxUint8())
}

Output:

Value of math.MaxUint8: 255
