Atan2

WebATAN2 function Description. Arc tangent of two numbers, or four-quadrant inverse tangent. ATAN2(y, x) returns the arc tangent of the two numbers x and y. It is similar to … WebFunction 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.
