WebMar 14, 2024 · Video. atan2 (y, x) returns value of atan (y/x) in radians. The atan2 () method returns a numeric value between – and representing the angle of a (x, y) point and positive x-axis. 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 …

If X ≠ 0, the result approximates arctan(Y/X). If Y > 0, the result is positive. If Y < 0, the result is negative. If X = 0, the absolute value of the result is PI /2. The -qxlf2003=signdzerointr option controls whether you get Fortran 2003 behavior. See qxlf2003
Webatan2 - Script command. Calculates the inverse trigonometric tangent function (arctangent) of y/x, returning the angle in the correct quadrant. Angle units are in radians. The function is defined for real values only. x,y must be real. The range of atan2 is - π to π .
