Parameters. Return Value. This function returns the principal arc tangent of The C ATAN2 Function is a C Math Library Function, used to calculate the Trigonometric Arc Tangent of y/x. Or you can say it returns the angle in radius from the X-Axis to the specified point (y, x).

In this Java program, We find the same with both positive and negative values and display the output. C 库函数 - atan2() C 标准库 - 描述 C 库函数 double atan2(double y, double x) 返回以弧度表示的 y/x 的反正切。y 和 x 的值的符号决定了正确的象限。 声明 下面是 atan2() 函数的声明。 double atan2(double y, double x) 参数 x -- 代表 x 轴坐标的浮点值。 y -- 代表..


If you imagine a ray starting from the origin of the coordinate system and extending outwards, every point along the ray will return the same angle value. RETURN VALUES. The atan2() function returns the arc tangent of y/x, in the range [-pi, +pi] radians.. If both y and x are 0.0, the result is undefined.

This function is defined in header file. [Mathematics] tan -1 (y/x) = atan2 (y, x) [In C++ Programming] 2018-07-26 2016-09-16 ATAN2(x_num, y_num) The ATAN2 function syntax has the following arguments: X_num Required. The x-coordinate of the point. Y_num Required. The y-coordinate of the point. Remarks. A positive result represents a counterclockwise angle from the x-axis; a negative result represents a clockwise angle.

C atan2 function

The Excel ATAN2 function returns the arctangent from the x and y coordinates of a point. In geometric terms, the function returns the radian angle corresponding to the coordinates of the input point. If you imagine a ray starting from the origin of the coordinate system and extending outwards, every point along the ray will return the same angle value.

Notes. The vector versions of the math functions operate component-wise. The description is per-component. C library function atan2() - Learn C programming language with examples using this C standard library covering all the built-in functions. All the C functions, constants and header files have been explained in detail using very easy to understand examples. The ATAN2 function returns the arc tangent (inverse tangent) of two numeric variables. The result of this function is similar to the result of calculating the arc tangent of argument-1 / argument-2, except that the signs of both arguments are used to determine the quadrant of the result.

Other C functions that are similar to the atan function: acos function asin function atan2 function cos function sin function tan function … The C atan2() function returns the angle theta from the conversion of rectangular coordinates (x, y) to polar coordinates (r, theta). The return value will be in the range -휋 through 휋. Syntax 4) Type-generic macro: If the argument has type long double, atanl is called. Otherwise, if the argument has integer type or the type double, atan is called. Otherwise, atanf is called. If the argument is complex, then the macro invokes the corresponding complex function (catanf, catan, catanl). C++ Math atan2() The function finds the inverse tangent of a coordinate.
