math.Y0() Function in Golang With Examples
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 order-zero Bessel function of the second kind with the help of Y0() 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 Y0() function.
Syntax:
func Y0(a float64) float64
- If you pass +Inf in this function like Y0(+Inf), then this function will return 0.
- If you pass 0 in this function like Y0(0), then this function will return -Inf.
- If the value of a<0, then this function will return NaN.
- If you pass NaN in this function like Y0(NaN), then this function will return NaN.
Example 1:
package main
import (
"fmt"
"math"
)
func main() {
res_1 := math.Y0(-3)
res_2 := math.Y0(6)
res_3 := math.Y0(math.Inf(1))
res_4 := math.Y0(math.NaN())
res_5 := math.Y0(4.6)
res_6 := math.Y0(0)
fmt.Println( "Result 1: " , res_1)
fmt.Println( "Result 2: " , res_2)
fmt.Println( "Result 3: " , res_3)
fmt.Println( "Result 4: " , res_4)
fmt.Println( "Result 5: " , res_5)
fmt.Println( "Result 6: " , res_6)
}

Output:
Result 1: NaN
Result 2: -0.28819468398157916
Result 3: 0
Result 4: NaN
Result 5: -0.22345995255364678
Result 6: -Inf
Example 2:
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Y0(5.89)
nvalue_2 := math.Y0(5)
res := nvalue_1 + nvalue_2
fmt.Printf( "%.3f + %.3f = %.3f" ,
nvalue_1, nvalue_2, res)
}
|
Output:
-0.306 + -0.309 = -0.614
