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 … WebReturns the arctangent, or inverse tangent, of the specified x- and y-coordinates. The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates (x_num, y_num). The angle is given in radians between -pi and pi, excluding -pi. Syntax. ATAN2(x_num,y_num) X_num is the x-coordinate of the point.

WebDec 1, 2024 · Remarks. The atan function calculates the arctangent (the inverse tangent function) of x.atan2 calculates the arctangent of y/x (if x equals 0, atan2 returns π/2 if y is positive, -π/2 if y is negative, or 0 if y is 0.). If you use the atan or atan2 macro from , the type of the argument determines which version of the function is … WebThe atan() and atan2() functions calculate the arctangent of x and y/x, respectively. Return Value. The atan() function returns a value in the range -π/2 to π/2 radians. The atan2() function returns a value in the range -π to π radians.
