If x and y are Function atan2() takes two arguments: x-coordinate and y-coordinate, and calculate the angle in radians for the quadrant. For better understanding of atan2(): [Mathematics] tan-1 (y/x) = atan2(y,x) [In C programming] Two other functions atan2f() and atan2l() are also present in C to specifically work with float and long double respectively. atan2 C Library Function The function double atan2 (double y, double x); returns the arc tangent of y/x, expressed in radians. Function atan2 takes into account the sign of both arguments in order to determine the quadrant.

In C++, this function is overloaded in (see valarray atan2 ). C99. // This example demonstrates Math.Atan() // Math.Atan2() // Math.Tan() using namespace System; int main() { double x = 1.0; double y = 2.0; double angle; double radians; double result; // Calculate the tangent of 30 degrees. In case you need more precision, there is a 3rd order rational function: normalized_atan(x) ~ ( c x + x^2 + x^3) / ( 1 + (c + 1) x + (c + 1) x^2 + x^3) where c = (1 + sqrt(17)) / 8. which has a maximum approximation error of 0.00811º C++ atan2 () The atan2 () function in C++ returns the inverse tangent of a coordinate in radians. This function is defined in header file. [Mathematics] tan -1 (y/x) = atan2 (y, x) [In C++ Programming] ATAN2 function Description.

radar displays with a variety of military functions and situational awareness capabilities, ECDIS, Description, This program calculates the atan2 function in either degrees or radians for both input and output. Author, Anthony C (anthonytc@email.com). These functions give the obvious trigonometric functions.
