If the +point is far enough, then the iteration immediately stops and the starting +point on the screen will be painted with a given colour, depending on the +fractal type and many other settings. + +For the :ref:`Mandelbrot set <mandel>` this value is 4. Other fractal types +usually have the same bailout value. For most fractals many bailout values give +more or less similar output. E.g., for the second order Mandelbrot set one can +prove that the sequence \|z\| (z:=z^2+c) tends to infinity if and only if \|z\|>2 +for some element z of this sequence. In XaoS program, Bailout value is the +square of this 2, i.e. you can change this to any value greater than 2 for +similar results. + +Other fractal types may use other bailout values. The default is 4 for each +types. + +**Available as**: menu item, command line option, command + +**Syntax**:(bailout float) |
