[Mathematics] tan -1 (y/x) = atan2 (y, x) [In C++ Programming] atan2 () prototype [As of C++ 11 standard] atan2 (y,x) Returns the principal value of the arc tangent of y/x, expressed in radians. Notice that because of the sign ambiguity, a function cannot determine with certainty in which quadrant the angle falls only by its tangent value (atan alone). You can use atan2 if you need to determine the quadrant. ATAN2 (y, x) returns the arc tangent of the two numbers x and y. It is similar to calculating the arc tangent of y / x, except that the signs of both arguments are used to determine the quadrant of the result. The result is an angle expressed in radians. To convert from radians to degrees, use the DEGREES function.

A positive result represents a counterclockwise angle from the x-axis; a negative result represents a clockwise angle. ATAN2(a,b) equals ATAN(b/a), except that a can equal 0 in ATAN2. C言語の関数リファレンス(atan2 - y/x逆正接の計算)。 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.. The atan2() function returns a value in the range -π to π radians. If both arguments of the atan2() function are zero, the function sets errno to EDOM, and returns a value of 0. Example that uses atan() This example calculates arctangents using the atan() and atan2() functions. 在C语言的math.h或C++中的cmath中有两个求反正切的函数atan(double x)与atan2(double y,double x) 他们返回的值是弧度 要转化为角度再自己处理下。 atan2 double atan2(double , double ); calculates arctangent from 2 numbers C Sourcecode Example compile in linux with: gcc atan2.c -o atan2 -lm -Wall #include /* including standard library */ //#include /* uncomment this for Windows */ #include /* including math library */ int main ( void ){ double a=1.2, b=-2.6 atan2() 関数は -π から π ラジアンの範囲の値を戻します。atan2() 関数の両方の引数がゼロの場合、この関数は errno に EDOM を設定し、0 を戻します。 atan() の使用例.

Arc tangent is the inverse operation of tangent atan2 in c is used to find arc tangent in radians of y/x based on signs of both values that determine the correct quadrant. atan in c is a mathematical function that is used to find the arc tangent value of a given number in radians. atan2 takes two input parameters as x and y co-ordinates. atan takes one input parameter.
