Data. Array of values;

AscendingOrder. Method of arrangement:

True. A number rank is determined as if an array has been sorted in the descending order.

Example

To execute the example, add a link to the Stat system assembly.

Sub UserProc;
Var
    st: Statistics;
    d0: Double;
    y: Array Of Double;
Begin
    y := New Double[10];
    y[00] := 2.8;
    y[01] := 1.7;
    y[02] := 2.3;
    y[03] := 1.9;
    y[04] := 2.1;
    y[05] := 0.4;
    y[06] := 2.2;
    y[07] := 1.8;
    y[08] := 2.4;
    y[09] := 1.6;
    st := New Statistics.Create;
    d0 := st.Rank(2.2,y,True);
    Debug.WriteLine("Rank: " + d0.ToString);
End Sub UserProc;

Executing the example shows the rank of the specified number in the console window:
