Polar angle of a point
Find the polar angle of the point.
Two integers are given - the decart coordinates of the point that does not coincide with the origin. Input values do not exceed 10000 by the absolute value.
Print one real number - the value of its polar angle in radians in the interval [0; 2π). The answer must be rounded to 6 digits after the decimal point.
