go math.Y0()
math.Y0()方法语法
func Y0(x float64) float64
go源码对Y0()方法的介绍：
Y0 returns the order-zero Bessel function of the second kind.
Special cases are:
Y0(+Inf) = 0
Y0(0) = -Inf
Y0(x < 0) = NaN
Y0(NaN) = NaNgolang标准库math.Y0()方法，返回x的0阶的第二类贝塞尔函数。除此之外，Y0(+Inf) = 0；Y0(0) = -Inf；Y0(x < 0) = NaN；Y0(NaN) = NaN。
math.Y0()方法实例代码
func main() {
y0 := math.Y0(1.3)
fmt.Println(y0)
}运行go文件，得到输出：
