title: Calculate Mandelbrot set for greater precision
body: <p>Is there any practical way to perform calculations such as those involved in generating the Mandelbrot Set for values for precise that what <code>double</code> or <code>long double</code> can provide? I was thinking of possibly having two variables(either double or long), one storing the value similar to scientific notation and the other storing the negative log10 of the value, but I'm not sure if there would actually be a way to perform the calculation like this.</p>
