Publisher Description
"What numbers did I input?” "Was the number I input correct?” Everyone must have caught on such anxiety while using a calculator.
SmartCalc is a calculator that wipes out such anxiety.
Because, after a calculation, inputs are displayed as you input, and also one input number can be changed for the next calculation.
[Instructions]
. To recall calculation history, tap "＜ Prev" key until you find the history you want. After you tapped "＜ Prev" key, if you want to recall a newer history, tap "Next ＞" key until you find it.
. To clear the calculator completely including calculation history, close SmartCalc.
. To clear the calculator except for the set memory and the independent memory on MR-line, tap "C" key and then tap "AC" key appeared, that is, double tap "C" key.
. To clear the independent memory on MR-line, tap "MR" key and then tap "MC" key appeared, or swipe on MR-line.
. To completely clear the number you have just input on 1st-line or 2nd-line, tap "C" key.
. To erase a right end number at 1st-line or 2nd-line framed in the input mode, swipe on the line.
. To change one of input numbers after a calculation, please tap the input line display to input a new number.
. Tapping Result-line display is a convenient substitute for tapping "=" key.
[Features]
. SmartCalc is a calculator with a large 4-line display, which consists of 1st-line, 2nd-line, Result-line and MR-line. As all numbers related to a calculation are displayed on the lines all together, a user can check the calculation at a glance.
. SmartCalc doesn't require any special operations. Anyone can use SmartCalc easily.
. SmartCalc equips the set memory in addition to the general independent memory. The set memory automatically memorizes calculation history of all sets of calculated input numbers, an arithmetic operator and a result number.
. Can be used in environments where either a period or a comma is used as the decimal separator.
