result |
The arctangent of value. |

value |
The value you want the arctangent of. |
Notes
The Atan function returns the angle (in radians) of the number passed to it. To express the arctangent in degrees, multiply the result by 180/PI.
Sample code
This example uses the Atan function to return the arc tangent of a number.
Var d As Double
Const Pi = 3.14159265358979323846264338327950
d = Atan(1) // returns 0.785398 (PI/4 radians)
d = Atan(1) * 180 / Pi // returns 45
