Calculator, no rounding errors

FEATURES:

1. Accurate, no round-off errors

- Computational error (rounding-off) doesn't occur.

This app treats a numerical value as a rational number of the infinite precision.

e.g.

A result of "1 ÷ 3" is indicated as "0.3333333...",

but is internally treated as "1/3" (fraction).

2. Arithmetic operator precedence

- This app understands the arithmetic operator precedence.

(e.g. Multiplication precedes addition.)

Thus, in the expression "1000 ＋ 25 × 8",

the answer is "1200" (not "8200").

- This app also understands parentheses.

Thus, in the expression "1 ÷ ( 2 ＋ 3 )",

the answer is "0.2" (not "3.5").

3. Infinite-precision arithmetic

- This app can deal with a very huge numbers or

very tiny numbers without errors.

- When a number is too long and doesn't fit into the display area,

you can scroll the display area horizontally.

- When the quotient is not divisible,

it is shown up to 24 digits after the decimal point.

4. Percentage operations

- You can use the "％" button to calculate a tax, etc.

e.g.

"200 ＋ 8 ％" means "200 ＋ (200 × 0.08)".

Thus, its result is "216".

5. "00" button and "000" button

- You can use the "00" button instead of pressing the "0" button twice.

- You can also use the "000" button instead of pressing the "0" button 3 times.

However, the "000" button is available only in the landscape mode.

6. Hardware keyboard

- You can input a numerical value with the hardware numeric keypad of your terminal.

- You can also input a numerical value with the hardware keyboard which is connected to your terminal.

7. Free of charge, no advertisements

- You can use this app free of charge.

- There is no advertisements in this app.

8. No permissions required

- This app doesn't require any permissions.
