math package of GO provides a Min method that can be used to get the minimum of two numbers. The

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

func Min(x, y float64) float64

Also some special cases of Min function are

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

Code:

package main

import (
    "fmt"
    "math"
)

func main() {
    min := math.Min(2, 3)
    fmt.Println(min)

    min = math.Min(-2.1, -3.3)
    fmt.Println(min)
}

Output:

2
-3.3
