Visual size of Square ??

[Redee]

If I create RectangleShape(10.5001f, 10.5001f) - see on monitor square with size of 11px width and 10px height.
Created RenderWindow with size 800x800.

Why not 11px / 11px square.
If I set 10.501f / 10.501f - got square 11 / 11.
But me need 4 signs precision after point.

Because of OpenGL rasterisation.

Thats why need store 2 sizes of Object >>
1 - logic math
2 - whole number without signs after point to Display

Using f.e. >> floor(x + 0.5f);
