This is a calculator to perform simple percent calculations.
At the top of the form one value (value 1) is specifies, another value (value 2) at the bottom,
in the middle there are details of the difference between the values with

value 1 + difference = value 2
**Usage:**
Type two of the seven values into their corresponding fields (no matter which order).
After a click on any free space of the window or the "calculate" button,
the calculation is performed. Read the results.

The calculation is done using the two values changed last as input.
After the calculation these fields are coloured in light green while the calculated results
are coloured in light pink.
For another calculation with only one changed input value, just type the changed value.
For another calculation with completely new values, click on the "reset" button
before input.

**Example:** Some goods cost 89.90 € and the price includes 19 % value added tax.
Since the price is the sum of the net-price and the tax amount, type "89.90"
into the field for value 2 at the bottom.
The value added tax is calculated relative to the net price.
Therefore, type "19" into the field "% of value 1" in the middle
and click on any empty space of the window or the "calculate" button.
Now you may read the results: The net price "value 1" is 75.55 €,
the amount of value added tax is 14.35 € (value of the difference).
The net price is lower by 15.97 % ("% of value 2 " in the middle).
The net price corresponds to 84.03 % of the gross price (top right), while the
gross price is 119 % of the net price (bottom right).
