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:
// 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:
// 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
