+## Rounding
+
+Székely Balázs has provided code for rounding towards positive infinity per the original challenge.\
+This will be the official way to round the output values:
+```pas
+function TBaseline.RoundEx(x: Double): Double;
+begin
+  Result := PascalRound(x*10.0)/10.0;
+end;
+
+function TBaseline.PascalRound(x: Double): Double;
+var
+  t: Double;
+begin
+  //round towards positive infinity
+  t := Trunc(x);
+  if (x < 0.0) and (t - x = 0.5) then
+  begin
+    // Do nothing
+  end
+  else if Abs(x - t) >= 0.5 then
+  begin
+    t := t + Math.Sign(x);
+  end;
+
+  if t = 0.0 then
+    Result := 0.0
+  else
+    Result := t;
+end;
+```
