atan2

Arc tangent of two variables

&reftitle.description; `float` `atan2` `float` `y` `float` `x`

This function calculates the arc tangent of the two variables `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 function returns the result in radians, which is between -PI and PI (inclusive).

&reftitle.parameters;

`y`

- Dividend parameter

`x`

- Divisor parameter

&reftitle.returnvalues;

The arc tangent of `y`/`x` in radians.
