My Mandelbrot Set Calculator ver1.0

The image of Mandelbrot Set is one of the most famous fractal in mathematics,

and is generated as follows.

  (1) Calculating the following recurrence formula for each pixel.

         Zn+1 = Zn * Zn + c    (n=0,1,2 ...)

         Z0 = 0

         (c: corresponding complex number for each pixel)

  (2) Determine the color of this pixel based on its convergence for above calculation.

Especially you can find beautiful and mysterious images at more than1000x zoom

on the boundary of its initial image.

This app enables you to enjoy the image of Mandelbrot Set easily on your palm top

thanks to the computing power of ios devices.

Especially by executing above calculation for each zoom-in operation, same image quality

is kept even for more than 1000x zoom.

You can also save your favorite image to Photos, and use this as wallpaper or t-shirts design.

"Dr Fraction", "Dr Fraction for iPad" (CLOSE)

"Dr. Fraction" and "Dr Fraction for iPad" have closed due to the release of "Dr. Fraction Special".
As "Dr. Fraction Special" support all functions that "Dr, Fraction" and "Dr Fraction for iPad" have,   could you please use "Dr. Fraction Special" from now.

Thanks and Best Regards

Dr Fraction Special ver 1.1

More natural fractional calculation process has come true by improved algorithm.
The operation method is same with current version 1.0.

Thanks and Best Regards

Dr Fraction Special ver 1.0

This app is a special version for the current 'Dr Fraction' or 'Dr Fraction for iPad',
and has following features.

- Fractional expression with missing number is also acceptable.
- Font size adjustment according to the length of  expression.
    (Large font size for short expression and small font size for long expression.)
- Other User Interface Improvement for iOS7.
    (This app is designed for both iPhone and iPad, and only for iOS7.)

The operation flow is similar with current apps.

(1) Normal Fractional calculation

The initial stage is as follows. We can always jump to this stage by touching "Reset".

Then we will proceed with expression input process by touching numbers and operational pads.

We can enter fraction input mode by touching "b/a" or "c b/a" as follows.

Once the fractional expression input complete, touch "Go" to start calculation mode as follows.

The following is one of the calculation scene.  Step by step calculation is easy to understand.

The following is the scene when calculation is over.
At this time, you can go backward and confirm previous calculation precess again
by touching upwards arrow.

Touch "Reset" to start another calculation.

(2) Calculation with a missing number.

Following is one example.
(You can specify missing number only once, and only in the left side of an expression.)

By repeating 'Go', you can get the following result.

(3) Font size adjustment

Following is one example.
Small font size is used for long expression, on the other hand large font size is used for short
expression.

Thanks and Best Regards
