Accurate, easy-to-use, and no permissions required
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.
