Golang math.Min() function is “used to find the smaller of two float64 values”. It accepts two float64 values as parameters and returns the minimum.
To add a math package to your program, use the “import” keyword to access the “Min()” function.
Syntax
func Min(x, y float64) float64Parameters
It accepts two arguments from which we need to find a minimum number.
Return value
The Min() function returns -Inf if you pass -Inf to Min(-Inf, b) or Min(a, -Inf).
The Min() function returns NAN if you pass NAN to Min(NAN, b) or Min(a, NAN).
The Min() function returns -0 if -0 or 0 as in Min(-0, 0) or Min(0, -0).
Example 1: How to Use math.min() function
package main
import (
"fmt"
"math"
)
func main() {
min := math.Min(19.0, 21.0)
fmt.Println("The minimum number is: ", min)
}The minimum number is: 19Example 2: Passing NaN, Inf, 0, -0
package main
import (
"fmt"
"math"
)
func main() {
op1 := math.Min(0, -0)
op2 := math.Min(math.NaN(), 21)
op3 := math.Min(math.Inf(1), 19)
fmt.Println("The minimum number is: ", op1)
fmt.Println("The minimum number is: ", op2)
fmt.Println("The minimum number is: ", op3)
}
Output
The minimum number is: 0
The minimum number is: NaN
The minimum number is: 19Example 3: Using the float64() function
package main
import (
"fmt"
"math"
)
func main() {
x := 19
y := 21
min := math.Min(float64(x), float64(y))
fmt.Println("The minimum number is: ", min)
}Output
The minimum number is: 19Example 4: Finding minimum of float64 values in a slice
package main
import (
"fmt"
"math"
)
func main() {
data := []float64{21.0, 29.0, 19.0, 46.0}
min := data[0]
for _, value := range data {
min = math.Min(min, value)
}
fmt.Println("The minimum number is: ", min)
}
Output
The minimum number is: 19That’s it!
