Could you please explain more to me what is the difference between PointF and Point in .NET?

I thought the coordinates of pixels on screen are calculated as integers only, so what can PointF do anything special here?

In fact, in some cases I have to use PointF instead of Point to have some shape drawn with higher quality, but in some case using PointF doesn't make any difference.

Your help would be highly appreciated!

Why asking such questions? Anyone can see the declaration of one and another. The questions about "difference" are generally incorrect. If you don't understand it, tell us the difference between apple and Apple. :-)

I mean the difference in usages of the both not in declarations (Why and when using PointF instead of Point ? Don't you think this is a must understand matter for everyone who programs with GDI+ in .NET?). Thanks!

Thank you, the answers from that link can tell me at least a reason for PointF to be used in .NET, but I still don't know how it works differently from Point because as I said that our screen is divided into many rectangular pixels and coordinates are integers. Please wait more for other answers... before I accept your solution. Thanks again!!!
