Finding Minimum of Two Numbers in Golang
Last Updated :

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:
package main
import (
"fmt"
"math"
)
func main() {
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)
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:
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Min(34, 67)
nvalue_2 := math.Min(56.7, 90.8)
res := nvalue_1 + nvalue_2
fmt.Printf( "%.2f + %.2f = %.2f" ,
nvalue_1, nvalue_2, res)
}
|
Output:
34.00 + 56.70 = 90.70
