math.Yn() Function in Golang With Examples Last Updated : 13 Apr, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report 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: C // Golang program to illustrate // the use of math.Yn() function package main import ( "fmt" "math" ) // Main function func main() { // Finding the order-n Bessel // function of the second kind // Using Yn() function 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) // 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) } Output: Result 1: NaN Result 2: -5.436470340703773 Result 3: -0.698119560067667 Result 4: NaN Result 5: +Inf Example 2: C // Golang program to illustrate // the use of math.Yn() function package main import ( "fmt" "math" ) // Main function func main() { // Finding the order-n Bessel // function of the second kind // Using Yn() function nvalue_1 := math.Yn(3, 4) nvalue_2 := math.Yn(5, 6) // Sum of the given numbers res := nvalue_1 + nvalue_2 fmt.Printf("%.3f + %.3f = %.3f", nvalue_1, nvalue_2, res) } Output: -0.182 + -0.197 = -0.379 Comment More infoAdvertise with us Next Article math.Y0() Function in Golang With Examples K Kirti_Mangal Follow Improve Article Tags : Go Language Golang-Math Similar Reads math.Y1() 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.
