WebApr 2, 2024 · 1-3) Computes the arc tangent of y / x using the signs of arguments to determine the correct quadrant. The library provides overloads of std::atan2 for all cv-unqualified floating-point types as the type of the parameters y and x. (since C++23) WebDescription. Returns the angle in radians whose Tan is y/x. Return value is the angle between the x-axis and a 2D vector starting at zero and terminating at (x,y). Note: This function takes account of the cases where x is zero and returns the correct angle rather than throwing a division by zero exception.
