2 | ||
3 | **PocketCalclator** is first of all a study to identify the possiblities to develop simple software tools for mobile devices. These tools shall be platform indipendant, thus it runs entirely on HTML and Javascript | |
4 | ||
5 | ### Application Taschenrechner | |
6 | ||
7 | As application, this program *Taschenrechner.html* can ben used by mouse or touchscreen clicks as well as via a keyboard. | |
8 | ||
9 | The bottom line serves to input the numbers. The functions (currently root/square/ln) also operate on this number. Once an operator (#-/*) is pressed it is copied to the first line where the formular is shown. | |
10 | ||
11 | Pressing "=" calculates the result, which is shown in the middle line. | |
12 | ||
13 | The following keys are available: | |
14 | ||
15 | * e: to enter exponentials, such as `1e3` which stands for 1*10^3 | |
16 | * "DEL" or key `backspace`: deletes last digit. | |
17 | * "C" or key `ESC`: deletes input number, formular and result display | |
18 | * "√" or key "r": calculates the root of the number in the input field | |
19 | * "x²" or key "S": calculates the square of the number in the input field | |
20 | * "ln" or key "l": calculates the natural logarithm of the number in the input field | |
21 | * "STO" or key "s": stores the result to memory | |
22 | * "RCL" or key "m": recalls the results from memory | |
23 | * "ANS" or key "a": recalls the last result | |
24 | * "=" or key "Enter": provides the result of the formular | |
25 | * "ENG" or key "n": toggles notation between exponential and floating point display | |
