std::hypot, std::hypotf, std::hypotl - cppreference. com 1-3) Computes the square root of the sum of the squares of x and y, without undue overflow or underflow at intermediate stages of the computation The library provides overloads of std::hypot for all cv-unqualified floating-point types as the type of the parameters x and y (since C++23)
Math. hypot () - JavaScript - MDN Because hypot() is a static method of Math, you always use it as Math hypot(), rather than as a method of a Math object you created (Math is not a constructor)
numpy. hypot — NumPy v2. 4 Manual Given the “legs” of a right triangle, return its hypotenuse Equivalent to sqrt(x1**2 + x2**2), element-wise If x1 or x2 is scalar_like (i e , unambiguously cast-able to a scalar type), it is broadcast for use with each element of the other argument (See Examples) Leg of the triangle (s)
为什么 C++ 中 std::hypot (x, y) 函数很慢？ 用途 hypot 是单词 hypotenuse 的缩写，意为直角三角形的斜边。 std::hypot (x, y) 是在计算 x 2 + y 2 ，式子的意义为直角三角形斜边的长、平面上两点的距离、二维向量的模、复数 (x, y) 的模长（std::complex 的 abs 函数的内部实现，就是在调用 hypot）等。
