Description
Returns the arctangent of the value specified. The arctangent is the angle whose tangent is value.
Usage
result = ATan(value)

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
