The ATAN function is a mathematical function that returns the angle (in radians) from the x-axis to a point (y,x). This is sometimes referred to as ATAN2.
| Function Name |
ATAN (also known as ATAN2). |
| Description |
Returns the angle from the x-axis to a point (y, x). |
| Arguments |
ATAN(Y, X) Where Y is a REAL or INTEGER that represents a cartesian y coordinate, and X is a REAL or INTEGER that represents a cartesian x coordinate. For information on integers and real floating values—see Number (Integer or Real). When there are 2 inputs (y and x), the result is equivalent to y divided by x. ATAN (y, x) is equivalent to ATAN (y/x). |
| Returns |
REAL The output is the angle (in radians) from the x-axis to a point (y,x) |
Example:
ATAN(20, 3)
The output is 1.42 or the angle (in radians) from the x-axis to a point (y,x).
