math.Y0() 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 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
