hypot函数

C ++ hypot()函数 (C++ hypot() function)

hypot() function is a library function of cmath header, it is used to find the hypotenuse of the given numbers, it accepts two numbers and returns the calculated result of hypotenuse i.e. sqrt(x*x + y*y).

hypot()函数是cmath标头的库函数，用于查找给定数字的斜边，接受两个数字并返回斜边的计算结果，即sqrt(x * x + y * y) 。

Syntax of hypot() function:

hypot()函数的语法：

hypot(x, y);

Parameter(s): x, y – numbers to be calculated hypotenuse (or sqrt(x*x + y*y))

参数： x，y –要计算的斜边数(或sqrt(x * x + y * y) )

Return value: double – it returns double value that is the result of the expression sqrt(x*x + y*y).

返回值： double-它返回double值，该值是表达式sqrt(x * x + y * y)的结果 。

Example:

例：

Input:    float x = 10.23;    float y = 2.3;    Function call:    hypot(x, y);    Output:    10.4854

C ++代码演示hypot()函数的示例 (C++ code to demonstrate the example of hypot() function)

// C++ code to demonstrate the example of // hypot() function#include 
    
     #include 
     
      using namespace std;// main code sectionint main(){
       float x = 10.23;    float y = 2.3;    // calculate the hypotenuse     float result = hypot(x, y);    cout<<"hypotenuse of "<
      
       <<" and "<
       
        <<" is = "<
       
      
     
    

Output

输出量

hypotenuse of 10.23 and 2.3 is = 10.4854hypotenuse of 10.23 and 2.3 is = 10.4854
