Long Calculations
Depending on the speed of your device and the complexity of the calculation, some calculations may take a few seconds to complete. Generally in such cases, a dialog box containing "Calculating. . . " with a 'Cancel' button will be shown. You can stop the calculation by tapping and holding the cancel button.

powerOne Button
The powerOne button, in the top left corner of the display, offers access to logging functions, online help, product information, and calculator preferences. If the manual refers to the menu bar, you need to tap the menu button to make the menu bar visible. [. . . ] The templates contain a menu allowing values to be exported and the settings to be changed. See the section on Template & Variable Settings for more details.

Templates contain data in a columnar form as follows:
Label Column Selectable Label Variable Column
Evaluate Column
The first, or label, column contains the names of the variables. To enter a value, tap on the value column and enter it in the input screen. The

third, or evaluate, column contains "?" buttons next to variables that can be calculated. To compute a value, tap the "?" button next to the variable to be computed. Some templates offer multiple methods of looking at the same variable. For example, in the Tip template (shown above), the tip can either be an amount ("Tip$"), a percentage selected from a pop-up list ("Tip"), or a manually entered percentage ("Tip%").
Entering Data
In the templates, values are entered using the number input screen, date selector, or time selector, depending on the type of data requested. The date and time selectors are standard to the operating system on your device, used in applications such as the calendar and to do list. The number input screen is native to the powerOne line of calculators.
Number Input Screen
The number input screen is used to enter numerical values in the templates. When a value is selected, that value appears in the input screen:

from the Variable pop-up list. Selecting "Set All" will set all the variables to the current variable's preferences. Dec Setting: sets the displayed decimal places - float mode displays all available decimal places, 0-11 sets the decimal places to that number of places. Mode: numbers can be displayed in normal mode, scientific notation or engineering notation. A variable which is hidden will not be recalculated, even if Auto-Compute is checked. Global: if checked, allows the value of the variable to be shared with other templates. The equation variable is listed next to the 'Global' check box. In some cases this will be different than the displayed variable name (shown at the top of the page next to the 'Variable' label). For this variable to be shared with another template, the other template must contain the equation variable exactly as shown and its Global check box must also be checked. Range: available if the variable requires an iterative search to calculate its value. [. . . ] You should bill $137. 50 for your work.
