WebJul 14, 2012 · The standard atan and atan2 functions, as well as all other C functions that work with angles, work with radians, not degrees. If you want your own function to output degrees, you have to multiply the return value from atanf with 180/pi; to keep everything in radians, add pi instead of 180. Web1-3) Computes the principal value of the arc tangent of num. The library provides overloads of std::atan for all cv-unqualified floating-point types as the type of the parameter num.

WebFeb 12, 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 … WebNov 11, 2008 · The actual values are in radians but to interpret them in degrees it will be: atan = gives angle value between -90 and 90. atan2 = gives angle value between -180 … WebThe atan() function calculates the principal value of the arc tangent of x; that is the value whose tangent is x. Return Value On success, these functions return the principal value of the arc tangent of x in radians; the return value is in the range [-pi/2, pi/2]. e-620 レンズキット
