zooming in too much causes pixelation

[John Lutz]

Hi!

If I zoom into a Mandelbrot image too much it pixelates and
further zooming doesn't maintain a detailed image.

Is this because there is no more room on the stack?

Is there a way to fix this?

Thanks,
John

This is expected behavior.  Unless you'd like to recode the program to facilitate arbitrary precision, you're going to bump into the precision limit of 32 bit floating point calculation.  At some point you've zoomed in so far that the program cannot distinguish between values.
