math.MaxUint64 Constant

The MaxUint64 constant is an inbuilt constant of the math package which is used to get the highest (maximum) value that can be represented by a uint64 (unsigned int64).

The value of math.MaxUint64 constants is 1<<64 - 1 or 18446744073709551615.

Syntax

int math.MaxUint64

Parameters

• None

Return Value

The return type of math.MaxUint64 constant is int, it returns the highest (maximum) value that can be represented by a uint64.

Example 1

// Golang program to demonstrate the
// example of math.MaxUint64 Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.MaxUint64 is %T\n", math.MaxUint64)
	fmt.Println("Value of math.MaxUint64:", math.MaxUint64)
}

Output:

The result will be the highest value of a MaxUint64, 
the result may generate int overflow error.

Explanation:

In the above program, we imported the math package to use the math.MaxUint64 constant, then printed the type and value of the math.MaxUint64 constant.

Example 2

// Golang program to demonstrate the
// example of math.MaxUint64 Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of MaxUint64.
func getMaxUint64() int {
	return math.MaxUint64
}

func main() {
	fmt.Println("Value of math.MaxUint64:", getMaxUint64())
}

Output:

The result will be the highest value of a MaxUint64, 
the result may generate int overflow error.
