It would have been nice at the time of Delphi 1 in 1995 ... ;-)

A few weeks ago I got some havoc trying to port some code from LCL to 
Delphi 10.2 / FireMonkey when coordinates switch from Integer to Single, 
TPoint to TPointF,  array of TPoint to TPolygon...

I think you can't use integer value for mm or inches.
