WebJun 21, 2024 · The atan2 () is an inbuilt function in C++ STL which returns tangent inverse of (y/x), where y is the proportion of the y-coordinate and x is the proportion of the x-coordinate. The numeric value lies between – and representing the angle of a (x, y) point and positive x-axis. It is the counterclockwise angle, measured in radian, between the ...
