GammaFunc(Value: Double): Double;
Value. Value for which the Gamma function is calculated.
The GammaFunc property returns value of Gamma function for selected argument.
Value of parameter Value must be greater than zero.
To execute the example, add a link to the Stat system assembly.
Sub UserProc;
Var
st: Statistics;
d0, d: Double;
Begin
st := New Statistics.Create;
d := st.GammaFunc(4);
d0 := st.GammaLn(4);
If st.Status <> 0 Then
Debug.WriteLine(st.Errors);
Else
Debug.WriteLine("Value of Gamma function: " + d.ToString);
Debug.WriteLine("Natural logarithm of Gamma function: " + d0.ToString);
End If;
End Sub UserProc;
After executing the example the console window displays values of gamma function and natural logarithm of gamma function for selected argument.
