Atan

From Xojo Documentation

Method

Atan(Double) As Double

Supported for all project types and targets.

Returns the arctangent of the value specified. The arctangent is the angle whose tangent is value.


Syntax

result = Atan(value)

Part Type Description
result Double The arctangent of value.
value Double 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.


Examples

This example uses the Atan function to return the arc tangent of a number.

Dim d As Double
Const Pi = 3.14159265358979323846264338327950
d = Atan(1) // returns 0.785398 (PI/4 radians)
d = Atan(1) * 180 / Pi // returns 45
