math.Jn() Function in Golang With Examples
Last Updated :
13 Apr, 2020
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-n Bessel function of the first kind with the help of Jn() 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 Jn() function.
Syntax:
func Jn(a int, b float64) float64
Example 1:
package main
import (
"fmt"
"math"
)
func main() {
res_1 := math.Jn(1, math.Inf(-1))
res_2 := math.Jn(3, math.Inf(1))
res_3 := math.Jn(4, 5)
res_4 := math.Jn(1, math.NaN())
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: 0.39
Result 4: NaN
Example 2:
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Jn(2, 3.3)
nvalue_2 := math.Jn(4, 5.6)
res := nvalue_1 + nvalue_2
fmt.Printf( "%.2f + %.2f = %.2f" ,
nvalue_1, nvalue_2, res)
}
|
Output:
0.48 + 0.39 = 0.87
