WebThe atan() and atan2() functions calculate the arctangent of x and y/x, respectively. Return Value. The atan() function returns a value in the range -π/2 to π/2 radians. The atan2() …

WebAdditional overloads are provided in this header for other combinations of arithmetic types (Type1 and Type2): These overloads effectively cast its arguments to double before calculations, except if at least one of the arguments is of type long double (in which case both are casted to long double instead). This function is also overloaded in … WebMath.atan cannot tell the difference between the first and third quadrants, since the ratio, say, -1/-1 is the same as +1/+1. Nor will Math.atan work well if y=0, since division by 0 is not allowed. But Math.atan2 keeps the x and y arguments separated, so it can tell which quadrant the answer is in, and it can handle the case y=0.
