math.MaxUint Constant

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

The value of math.MaxUint constants is 1<<intSize - 1.

Note: intSize depends on the machine architecture. For example, if the machine is a 32-bit machine, intSize will be 4 bytes and if the machine is 64-bit, intSize will be 8 bytes.

Syntax:

int math.MaxUint

Parameter(s):

  • None

Return Value:

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

Example 1:

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

package main

import (
	"fmt"
	"math"
)

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

Output:

The result will be the highest value of a uint, 
the result may generate int overflow error.

Explanation:

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

Example 2:

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

package main

import (
	"fmt"
	"math"
)

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

func main() {
	fmt.Println("Value of math.MaxUint:", getMaxUint())
}

Output:

The result will be the highest value of a uint, 
the result may generate int overflow error.
