FEATURES:1. Accurate, no round-off errors- Computational error (rounding-off) doesnt 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 doesnt 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 doesnt require any permissions.
