Finding Minimum of Two Numbers in Golang

Last Updated : 13 Apr, 2020

Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You can find the smallest number among the given two numbers with the help of Min() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the Min() function. Syntax:

func Min(a, b float64) float64

If you pass -Inf in this function like Min(-Inf, b) or Min(a, -Inf), then this function will return -Inf.
If you pass NaN in this function like Min(NaN, b) or Min(a, NaN), then this function will return NaN.
If you pass -0 or +0 in this function like Min(-0, -0) or Min(-0, +0) or Min(-0, -0) or Min(+0, -0), then this function will return -0.

Example 1:

C

// Golang program to illustrate how
// to find the smallest number

package main

import (
    "fmt"
    "math"
)

// Main function
func main() {

    // Finding smallest number 
    // among the given numbers
    // Using Min() function
    res_1 := math.Min(0, -0)
    res_2 := math.Min(-100, 100)
    res_3 := math.Min(45.6, 8.9)
    res_4 := math.Min(math.NaN(), 67)

    // Displaying the result
    fmt.Printf("Result 1: %.1f", res_1)
    fmt.Printf("\nResult 2: %.1f", res_2)
    fmt.Printf("\nResult 3: %.1f", res_3)
    fmt.Printf("\nResult 4: %.1f", res_4)

}

Output:

Result 1: 0.0
Result 2: -100.0
Result 3: 8.9
Result 4: NaN

Example 2:

C

// Golang program to illustrate how
// to find the smallest number

package main

import (
    "fmt"
    "math"
)

// Main function
func main() {

    // Finding smallest number
    // among the given numbers
    // Using Min() function
    nvalue_1 := math.Min(34, 67)
    nvalue_2 := math.Min(56.7, 90.8)

    // Adding minimum numbers
    res := nvalue_1 + nvalue_2
    fmt.Printf("%.2f + %.2f = %.2f", 
           nvalue_1, nvalue_2, res)

}

Output:

34.00 + 56.70 = 90.70
