math.Jn() 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-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
