That's because it's banker's rounding, as previously established in this thread (correct?). When the fractional part is 0.5, banker's rounding rounds up if the integer part is odd and rounds down if the integer part is even. Your x1 has even integer part and x2 has odd integer part, hence ...

You wrote "...and using a double instead of an integer gives the correct results."

That's not really true. The integer version of the code (2 posts ago) gives the exactly correct answer up to the 92nd Fibonacci number. The double-precision code (previous post) only gives the exactly ...

With today's GHz processors, 100 is a small number, so I would guess that it is not a problem (and simple) to test the mouseclick coordinates against an array of rectangle coordinates. Of course that can be made more sophisticated, but a simple loop over all 100 possibilities is not unreasonable. I ...

Hi, I found this online:

At the bottom of the first post, click on "Here is the answer", and then scroll to the bottom of the first post in that thread where the full code is listed. It's in the Lua language but looks easy ...

It is not surprising that both dithering and using 4-bit depth add a lot of time to PNG compression. I doubt that it is a bug, it's just that those operations are expensive. As others have said, you can probably solve it by saving as JPG, or saving as PNG without dithering and using 24 or 32 bit ...

Thanks a lot, miso - that really helps. Very nice solution, and I like that the other operations can happen at a higher frequency than the renders.

Oh, I see. Was just starting to read up on 3D and hadn't noticed that FlipBuffers() is used with RenderWorld(). That answers my question, thanks.

I know about SetFrameRate(), which limits (on the upper end) the frame rate of FlipBuffers() in 2D, but it seems there is not an equivalent function for 3D (to limit the number of times RenderWorld() is called per second). Do I have to implement this frame rate cap myself? If so, what's the "best ...

miso/infratec - Thank you for the replies, they are helpful. I understand how double buffering works, but it is still unexpected that checking for events changes whether a FlipBuffers() is required. Perhaps it is because I'm checking for events inside a StartDrawing / StopDrawing block? Anyway, I ...

Hello, all. I'm a new user of PB on Windows (only 1 or 2 weeks), but an experienced programmer. The program below is a toy version of something I've been working on. The FOR loop simulates the fact that my real program will have a need, every so often, to draw graphics that will take some time, say ...
