Arrow loses its tip after PPI is greater than 144. Some combo boxes show it correctly thou.

Also I noticed in sCommonData.pas unit and function ScaleInt those Value * PPI div 96 should be MulDiv(Value, PPI, 96).

For example 11 * 120 div 96 = 13 but MulDiv(11, 120, 96) = 14.

Interesting. Why 14? Correct value is 13?
I didn’t knew about a difference between these two ways. I will research it and the issue with ComboBox scaling too.

11 * 120 = 1320
1320 / 96 = 13.75
Round(13.75) = 14

Yes, 1320 div 96 = 13.

If you take a look at any ChangeScale procedure in Vcl (TControl, TWinControl, etc.), all of them are using MulDiv.

[Support]

Interesting. It means that MulDiv works using a floating point calculations (slower).
I will think where to use it instead of “*” and “div”.
