About this app
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.
