Very small numbers

I am writing a Mandelbrot viewer. Everything works except when you get to a very high zoom the image starts to pixilate about at about zoom 10^(-14). I am guessing because i run out of memory in my double vars. What can i use that will allow me to use very sma开发者_JAVA技巧ll numbers?

I need to use the java.lang.Math class and i dont think that supports bigdecimal

If you really need arbitrary precision, your best option is probably BigDecimal.

If you're concerned with efficiency, I suspect you would be better off trying to scale your values and keep them in the neighborhood of 1.0.

The following discussion seems quite informative: High-Performance Arbitrary precision numerical calculations in Java (Mandelbrot Set!).

I know nothing about how you're doing it, but if you can do your calculations in log-space you can deal with tiny numbers much better (since they become large negative numbers).

You can use Java's BigDecimal.
