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 … WebATan2 converts rectangular coordinates (x,y) to polar (r,θ), where r is the distance from the origin and θ is the angle from the x-axis. Conversion of rectangular to polar coordinates. The equation for determining ATan2 is: tanθ = y / x (where θ is the angle). The ATan2 operation represents all quadrants in a Cartesian matrix (based on sign).

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() … WebIn computing and mathematics, the function atan2 is the 2- argument arctangent. By definition, is the angle measure (in radians, with ) between the positive -axis and the ray from the origin to the point in the Cartesian plane. Equivalently, is the argument (also called phase or angle) of the complex number.
