Just use WriteLn (Draw_GX_Min:3:16) and you get no mystery digits anymore...
In pretty much any programming language/compiler, if you print more digits than the precision of the used variable defines, you will get random numbers after the defined precision. This is not something FreePascal specific, any C/C++ compiler for example will do the same thing. People need to learn what limitations come along with floating point variables/calculations...
