Ultra Fractal can perform fractal calculations with almost any desired precision. This enables you to zoom as deep as you want, without hitting a precision limit. This is called arbitrary precision or deep zooming.
Three types of precision are available:
Ultra Fractal automatically selects the best precision type, depending on the current magnification and the selected fractal formula, transformations, and coloring algorithms. It calculates the number of decimals required and selects the fastest precision type that can support it.
You can verify the number of decimals required and the selected precision type in the General tab of the Statistics tool window.
Sometimes, you may want to adjust the number of decimals to force Ultra Fractal to use a different precision type, or to change the number of decimals used with the Arbitrary precision type. The Additional Precision input box on the Formula tab of the Layer Properties tool window allows you to do this.
The value in the Additional Precision input box is added to the default number of decimals required. Positive values will increase the precision; negative values will decrease it. Keep an eye on the Statistics tool window to see the effect.
