What is the function of atan2 in C++?
In C++, the atan2 function is a mathematical function used to calculate the arctangent value of two parameters. It takes two parameters, y and x, and returns the arctangent value of y/x. It can be used to calculate the corresponding radians based on the given y and x coordinates. This is commonly used for calculating angle values and directions, especially in computer graphics and robotics.
