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:
// Golang program to illustrate // the use of math.Y0() function package main import ( "fmt" "math" ) // Main function func main() { // Finding the order-zero Bessel // function of the second kind // Using Y0() function 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) // Displaying the result 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:
// Golang program to illustrate // the use of math.Y0() function package main import ( "fmt" "math" ) // Main function func main() { // Finding the order-zero Bessel // function of the second kind // Using Y0() function nvalue_1 := math.Y0(5.89) nvalue_2 := math.Y0(5) // Sum of the given numbers res := nvalue_1 + nvalue_2 fmt.Printf( "%.3f + %.3f = %.3f" , nvalue_1, nvalue_2, res) } |
Output:
-0.306 + -0.309 = -0.614
