Update Mandelbrot.pde

[l8l]

With the proposed changes, the plot of the Mandelbrot set will appear smoother than before. This is achieved by measuring how much the maximum threshold was exceeded by the final iteration of the Mandelbrot function z -> z^2 + z_0 at each point z_0.

A few small comments regarding using float instead of double, if they are ok with you, you can click "accept suggestion".

Thanks @shiffman . In this case, we only need float because the precision needed is small? If we'd implement a Mandelbrot with zoom function, would we need to use double instead?

[shiffman]

@l8l double would almost certainly be preferred for calculations like these and you are right I think that a higher degree of precision would be required when zoomed in! But for a basic Processing example like this one, I prefer to stick with float as "good enough" for ease / simplicity!

Thank you for this contribution!! ❤️
