math.J1() 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 find order-one Bessel function of the first kind with the help of J1() 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 J1() function. Syntax: func J1(a float64) float64 If J1(±Inf), then this function will return 0. If J1(NaN), then this function will return NaN. Example 1: C // Golang program to illustrate // the math.J1() function package main import ( "fmt" "math" ) // Main function func main() { // Finding order-one Bessel // function of the first kind // Using J1() function res_1 := math.J1(math.Inf(-1)) res_2 := math.J1(math.Inf(1)) res_3 := math.J1(4) res_4 := math.J1(math.NaN()) // Displaying the result fmt.Printf("\nResult 1: %.2f", res_1) fmt.Printf("\nResult 2: %.2f", res_2) fmt.Printf("\nResult 3: %.2f", res_3) fmt.Printf("\nResult 4: %.2f", res_4) } Output: Result 1: 0.00 Result 2: 0.00 Result 3: -0.07 Result 4: NaN Example 2: C // Golang program to illustrate // the math.J1() function package main import ( "fmt" "math" ) // Main function func main() { // Finding order-one Bessel // function of the first kind // Using J1() function nvalue_1 := math.J1(2.0) nvalue_2 := math.J1(4.1) // Sum of the given numbers res := nvalue_1 + nvalue_2 fmt.Printf("%.2f + %.2f = %.2f", nvalue_1, nvalue_2, res) } Output: 0.58 + -0.10 = 0.47 Comment More infoAdvertise with us Next Article math.Inf() Function in Golang With Examples K Kirti_Mangal Follow Improve Article Tags : Go Language Golang-Math Similar Reads math.J0() 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.
