Artboard spacing value looses precision
I use classic New Document dialog (it’s fast and reliable, unlike the modern one).
Within it, I can set a value that later would be used to space new artboards when adding ones, or to rearrange them.
If I only have one artboard (and I usually create one only, even when a project later gets more), I can’t set this value immediately, and the value gets transferred from the previous one I set there...
...not really. Here, I have to make it 2 artboards to have the field active (why? — I made another request to have it active — http://illustrator.uservoice.com/forums/333657/suggestions/51116134 — and one more before it, to have this value editable without workarounds — https://illustrator.uservoice.com/forums/333657/suggestions/43218936). Then, I make it 20 mm (and make it 1 artboard again)
After I create a document, I immediately create a new one — and it gets '19.999 mm' again.
I know some people in USA are used to have prices like $599. Screw it. I don’t need this applied to spacing. Yeah, sure it’s the math error. Make sure the value is kept as set.
