go Hypot()
Hypot()方法语法
func Hypot(p, q float64) float64
go源码对Hypot()方法的介绍：
Hypot returns Sqrt(p*p + q*q), taking care to avoid unnecessary overflow and underflow.
Special cases are:
Hypot(±Inf, q) = +Inf
Hypot(p, ±Inf) = +Inf
Hypot(NaN, q) = NaN
Hypot(p, NaN) = NaNgolang标准库math.Hypot()方法，可求取参数p²+q²的和的二次方根。除此之外，Hypot(±Inf, q) = +Inf；Hypot(p, ±Inf) = +Inf；Hypot(NaN, q) = NaN；Hypot(p, NaN) = NaN。
math.Hypot()方法实例代码
func main() {
hypot_num := math.Hypot(1.5, 2)
fmt.Println(hypot_num)
}运行go文件，得到输出：
2.5
