Fractional part of values.

Class
TMtxVec

Calculates the fractional part for X object elements [XIndex]..[XIndex+Len-1] and stores the result in calling object elements [Index]..[Index+Len-1]. An exception is raised if array borders are overrun or underrun.

---

Calculates the fractional part for all object values in-place.

Example 1

      var a: TVec;
        ind: Integer;
      begin
        a := TVec.Create;
        try
          a.SetIt(False,[1,5.5,-1.6,6]); // a = [1, 5.5, -1.6, 6]
          a.Frac;  // a = [0, 0.5, -0.6, 0]
        finally
          a.Free;
        end;
      end;
