Matlab atan2= 2.8438364863237604. C atan2= 2.8438364863237608. I have tried to even write mex files that implement the cos, sin and atan2, and I even put the whole computation that I am doing in a mex file and the result is the same. I have set the compiler of the mex file to be the same as the one from C and still, the difference is there.

On implementations without signed zero , or when given positive zero arguments, it is normally defined as 0. atan2 (y, x) is equivalent to carg (x + I * y). POSIX specifies that in case of underflow, y/x is the value returned, and if that is not supported, an implementation-defined value no greater than DBL_MIN, FLT_MIN, and LDBL_MIN is returned. The C library function double atan2(double y, double x) returns the arc tangent in radians of y/x based on the signs of both values to determine the correct quadrant. Declaration Following is the declaration for atan2() function.

It was initially used by the computer programming languages and now it has been used in various science and engineering fields. The results of the atan2 function will range between -π to +π.

Because C++ allows overloading, you can call overloads of atan and atan2 that take float or long double arguments.

atan = z/(1 .0f + 0.28f*z*z);.

So if p = y/x then to get α we'd use atan(p).
