Overview

math package of GO provides a Max method that can be used to get the maximum of two numbers.

Below is the signature of the function. It takes input two float numbers and returns a float.

func Max(x, y float64) float64

Also some special cases of Max function are

• Max(x, +Inf) = Max(+Inf, x) = +Inf
• Max(x, NaN) = Max(NaN, x) = NaN
• Max(+0, ±0) = Max(±0, +0) = +0
• Max(-0, -0) = -0

Code:

package main

import (
    "fmt"
    "math"
)

func main() {
    max := math.Max(2, 3)
    fmt.Println(max)

    max = math.Max(-2.1, -3.3)
    fmt.Println(max)
}

Output:

3
-2.1
