MaxInt, MinInt, MaxUint and MinUint in Go (golang)

main.go

package main

import "fmt"

// Constant definitions
const MaxUint = ^uint(0)
const MinUint = 0

const MaxInt = int(^uint(0) >> 1)
const MinInt = -MaxInt - 1

func main() {
	fmt.Println("Integer range on this computer")
	fmt.Println("MinUint:", MinUint)
	fmt.Println("MaxUint:", MaxUint)
	fmt.Println("MinInt:", MinInt)
	fmt.Println("MaxInt:", MaxInt)
}

Nice.

Nice!

nice

Release note Go 1.7: https://golang.org/doc/go1.17#math

The math package now defines three more constants: MaxUint, MaxInt and MinInt.

https://play.golang.org/p/5R2iPasn6OZ

package main

import "fmt"
import "math"

const maxUint = uint(math.MaxUint)

func main() {
	fmt.Println("Integer range on your system")

	// .Println("MaxUint:", math.MaxUint)  ERROR constant 18446744073709551615 overflows int
	fmt.Println("MaxUint:", maxUint)

	fmt.Println("MinInt:", math.MinInt)
	fmt.Println("MaxInt:", math.MaxInt)
}

finally, i kept forgetting the trick one. good bot !
