iReCalc is in reviewing process

This is a calculator which can calculate again after the answer was given.

Although there are multi-functional calculators, most likely they mean scientific calculator.

 So we have decided to create one that have functions we had wanted.

　When you calculate with a lot of numbers, you may find mistakes in the middle or after calculation.  In those cases, you have to do it again from the beginning. 

Or when you are at work, you notice that you do almost same calculation so may times.  So it might be easier if you can use same formula with variable numbers.

People use a spreadsheet application for this kind of tasks.  However, when you are out, or the task is not as big as something with switching on your PC, you may have to do it with your small calculator. 

iReCalc is designed to fit this kind of needs.

Here are some features:

1. Entered formula and answer remains in another window

2. Correct mistakes during or after calculation

3. Have a window that shows the formula vertically.  Easier to check when calculate with lots of numbers especially entering financial figures

4. Long formula can be displayed in multi line window

5. Windows size changeable, and show two windows at the same time

6. In ReCalc, re-calculation, mode, old formula can be called.  Then make some chage and re-calculate

7. Two formula saving windows.  One is just keeps every formula and answer, the other can keep  only the user wanted.  The user can call them any time and make some change, calculate again

8. Unneeded formula and answer can be erased

9. Variables are available.  For instance, call a formula A-(B+5)÷C then substitute 15 for A, 97-59 for B, and 8 for C

10. 16 colors of button and full color background and text choice

11. 8 types of font and 10 to 40 point text size choice
