“Big Number Calculator+” is an application that can calculate very large numbers.
The format that can be used is decimal (integer). The calculation functions that can be used are addition, subtraction, multiplication, and division. The number of digits is limited to 66000 digits. Only plus signs can be used. Minus signs cannot be used.
The calculation engine used in the calculation can be selected from “Swift” and “Objective-C”. You can also view the source code of the calculation engine. Please use at your own risk.
Only numerical values (1,2,3,4,5,6,7,8,9,0) are extracted from the input data. You can optionally enter non-numeric characters. It can be used as a delimiter.
It can be load from a file in addition to direct input.
Input data and calculation results are automatically formatted for printing and saving. The save file is saved in text format (.txt).

The app provides with a set of options to navigate through the Mandelbrot set in iPad. Starting from the initial range, you can zoom into a selected range and choose the color scheme and the maximum iterations. If you like the finding, you can save it for the furtuer navigation and/or share it.
* When first installed, an item with the default region will be created.
* Select an item from the list to see the Mandelbrot set within a region
- Color map, maximum iterations, and generator can be changed to generate a new image. Once updated, the save button will be enabled, so the changes can be saved.
* Click "Explore" to open a scene to navigate down the chosen region.
- The image on the right will display the region of the chosen item with a white box, which can be dragged and pinched.
- The image on the left will display the region within the white box.
- Color map, maximum iterations, and generator can be changed to recalculate the Mandelbrot set within the white box and to update the image on the left.
- If you like the result, you may save it to further navigate down.
- By clicking "Reset, the white box will be moved back to the original position with the original size.
- As navigating down to smaller regions, try to increase the maximum iterations and to use cpu as the generator, which would make it longer to generate a new image.
