math.Gamma() 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 Gamma function the given value with the help of the Gamma() 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 Gamma() function.
Syntax:
func Gamma(a float64) float64
- If Gamma(+Inf), then this method will return +Inf.
- If Gamma(+0), then this method will return +Inf.
- If Gamma(-Inf), then this method will return -Inf.
- If Gamma(a), then this method will return NaN for integer a<0.
- If Gamma(-Inf), then this method will return NaN.
- If Gamma(NaN), then this method will return NaN.
Example 1:
package main
import (
"fmt"
"math"
)
func main() {
res_1 := math.Gamma(math.Inf(-1))
res_2 := math.Gamma(math.Inf(1))
res_3 := math.Gamma(0)
res_4 := math.Gamma(1)
res_5 := math.Gamma(math.NaN())
fmt.Printf( "\nResult 1: %.1f" , res_1)
fmt.Printf( "\nResult 2: %.1f" , res_2)
fmt.Printf( "\nResult 3: %.1f" , res_3)
fmt.Printf( "\nResult 4: %.1f" , res_4)
fmt.Printf( "\nResult 5: %.1f" , res_5)
}
|
Output:
Result 1: NaN
Result 2: +Inf
Result 3: +Inf
Result 4: 1.0
Result 5: NaN
Example 2:
package main
import (
"fmt"
"math"
)
func main() {
nvalue_1 := math.Gamma(2)
nvalue_2 := math.Gamma(4)
res := nvalue_1 + nvalue_2
fmt.Printf( "%.2f + %.2f = %.2f" ,
nvalue_1, nvalue_2, res)
}
|
Output:
1.00 + 6.00 = 7.00
