math.Yn() Function in Golang With Examples
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 the order-n Bessel function of the second kind the help of Yn() 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 Yn() function.
Syntax:
func Yn(a int, b float64) float64
- If you pass +Inf in this function like Yn(a, +Inf), then this function will return 0.
- If the value of a≥0 like Yn(a≥0, 0), then this function will return -Inf.
- If the value of b<0 like Yn(a, b<0), then this function will return NaN.
- If the value of a<0 like Yn(a<0, 0), then this function will return +Tnf(if a is odd) or -Inf(if a is even).
- If you pass NaN in this function like Yn(a, NaN), then this function will return NaN.
Example 1:
package main
import (
"fmt"
"math"
)
func main() {
res_1 := math.Yn(-3, -2)
res_2 := math.Yn(6, 3)
res_3 := math.Yn(1, 1.1)
res_4 := math.Yn(1, math.NaN())
res_5 := math.Yn(-1, 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)
}

Output:
Result 1: NaN
Result 2: -5.436470340703773
Result 3: -0.698119560067667
Result 4: NaN
Result 5: +Inf
Example 2:
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Yn(3, 4)
nvalue_2 := math.Yn(5, 6)
res := nvalue_1 + nvalue_2
fmt.Printf( "%.3f + %.3f = %.3f" ,
nvalue_1, nvalue_2, res)
}

Output:
-0.182 + -0.197 = -0.379
