Acos
From Xojo Documentation
Method
Returns the arccosine of the value specified. The arccosine is the angle whose cosine is value. The returned angle is given in radians.
Usage
result = Acos(value)
| Part | Type | Description |
|---|---|---|
| result | Double | The arc cosine of value. |
| value | Double | The value you want the arc cosine of. |
Notes
The Acos function returns the angle (in radians) of the cosine passed to it. To convert the result from radians to degrees, multiply it by 180/Pi.
Sample Code
This example uses the Acos function to return the arc cosine of a number.
Var d As Double
Const Pi = 3.14159265
d = Acos(0.5) // returns 1.0471976
d = Acos(0.5) * 180 / Pi // returns 60
Const Pi = 3.14159265
d = Acos(0.5) // returns 1.0471976
d = Acos(0.5) * 180 / Pi // returns 60
