Finding Maximum of Two Numbers in Golang
Last Updated :
21 Nov, 2022
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 largest number among the given two numbers with the help of Max() 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 Max() function.
Syntax:
func Max(a, b float64) float64
- If you pass +Inf in this function like Max(+Inf, b) or Max(a, +Inf), then this function will return +Inf.
- If you pass NaN in this function like Max(NaN, b) or Max(a, NaN), then this function will return NaN.
- If you pass -0 in this function like Max(-0, -0), then this function will return -0.
- If you pass -0 or +0 in this function like Max(+0, -0) or Max(+0, +0) or Max(-0, +0) or Max(+0, +0), then this function will return +0.
Example 1:
Go
package main
import (
"fmt"
"math"
)
func main() {
res_1 := math.Max( 0 , - 0 )
res_2 := math.Max(- 100 , 100 )
res_3 := math.Max( 45.6 , 8.9 )
res_4 := math.Max(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: 45.6
Result 4: NaN
Example 2:
Go
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Max( 34 , 67 )
nvalue_2 := math.Max( 56.7 , 90.8 )
res := nvalue_1 + nvalue_2
fmt.Printf( "%.2f + %.2f = %.2f" ,
nvalue_1, nvalue_2, res)
}
|
Output:
67.00 + 90.80 = 157.80
