Value. Angle cosine.
The ACos method returns the arccosine of a number.
The Value parameter value cannot be empty and must belong to the [-1;1] interval.
To execute the example, add a link to the MathFin system assembly.
Sub UserProc;
Var
r: Double;
Begin
r := Math.ACos(-0.5);
Debug.WriteLine(r);
End Sub UserProc;
After executing the example the console window displays the arccosine of the specified number equal to 2.0943951023932.
