go Gamma()
Gamma()方法语法
func Gamma(x float64) float64
go源码对Gamma()方法的介绍：
Gamma returns the Gamma function of x.
Special cases are:
Gamma(+Inf) = +Inf
Gamma(+0) = +Inf
Gamma(-0) = -Inf
Gamma(x) = NaN for integer x < 0
Gamma(-Inf) = NaNgolang模块math.Gamma()方法，返回参数x的伽玛函数值，当x为正整数时，返回值为(x-1)!。除此之外，Gamma(+Inf) = +Inf；Gamma(+0) = +Inf；Gamma(-0) = -Inf；Gamma(x) = NaN for integer x < 0；Gamma(-Inf) = NaN；Gamma(NaN) = NaN。
math.Gamma()方法实例代码
func main() {
gamma_v := math.Gamma(3)
fmt.Println(gamma_v)
}运行go文件，得到输出：
