Golang program to find the smallest number between two numbers using math.Min() function

Here, we are going to learn how to find the smallest number between two numbers using math.Min() function in Golang (Go Language)?
Submitted by Nidhi, on February 15, 2021

Problem Solution:

In this program, we will find the smallest value between two numbers using math.Min() function and print the result on the console screen.

Program/Source Code:

The source code to find the smallest number between two numbers using math.Min() function is given below. The given program is compiled and executed successfully.

// Golang program to find the smallest number between two numbers 
// using math.Min() function.

package main
import "fmt"
import "math"

func main() {
    var num1 float64  = 10.25
    var num2 float64  = 20.14
    
    var small float64  = 0
   
    small=math.Min(num1, num2)
    
    fmt.Printf("Smallest number is : %f", small) 
}

Output:

Smallest number is : 10.250000

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use functions related to fmt package.

Here, we also included the math package to use math-related functions and created the main() function. The main() function is entry point for the program. Here, we created 3 floating-point variables num1, num2, small, which is initialized with 10.25, 20.14, 0 respectively.

Here, we used the Min() function of the math package to find the smallest number between two numbers and print the smallest number on the console screen.
