go Sqrt()
Sqrt()方法语法
func Sqrt(x float64) float64
go源码对Mod()方法的介绍:
Sqrt returns the square root of x.
Special cases are:
Sqrt(+Inf) = +Inf
Sqrt(±0) = ±0
Sqrt(x < 0) = NaN
Sqrt(NaN) = NaN
golang标准库的math.Sqrt()方法,接收一个参数x,并求取x的二次方根。除此之外,Sqrt(+Inf) = +Inf;Sqrt(±0) = ±0;Sqrt(x < 0) = NaN;Sqrt(NaN) = NaN。
math.Sqrt()方法实例代码
func main() {
sqrt_num := math.Sqrt(36)
fmt.Println(sqrt_num)
}
运行go文件,得到输出:
