TemplatesTemplates combine the what-if scenario analysis power of a calculator with the visual effect and easy entry of a simple spreadsheet. Each row of a template consists of three elements: a label, a value and an equals button (if the row can be computed).
Each template is available by selecting its title in the List.
Basic FunctionalityTo perform a computation enter the data you know then select the equals button on the row you don't. Enter data by selecting the desired row and entering its data in the displayed editor. To calculate select the equals button on the desired row. In some cases, however, the template can successfully predict what needs to be calculated. As each row is entered the equals button turns gray to indicate that it is known data. If enough data is known it will calculate automatically. (If the template is wrong you can override it by selecting a grayed out equals button.) Also note that some rows have beige backgrounds. This indicates that these rows are read-only.
Data TypesThere are four kinds of data available: Numbers, Tables, Dates and Lists. Number rows can either be decimal numbers, fractions or feet-inch. Each type has its own editor. Enter a number in the editor then select Save to save to the template. (On iPad you can select outside the editor to save.) Cancel will throw out any changes. See the Data Types section for additional details on data entry. The number editor -- for decimal, fraction and feet-inch entry -- also offers basic math capabilities. Select the "math" button to see available functions. In addition the number editor also has a button labeled "show". This button displays the full precision of calculated, rounded results. See Calculation Accuracy section below for details. Finally on an iPhone or iPod touch, the landscape calculator and number editor are integrated. See calculator for details.
Calculation AccuracyThe decimal places displayed in the template is different from the decimal places stored in the application to ensure calculation accuracy. For many template results you can see the full precision. Display it in the number editor then click 'show' once to show the full precision of the displayed value. Click it again to revert back to the displayed row's precision. (In fact, this button will also act as an undo, taking you back to the previously stored result.)
Help is integrated directly into the template. Select Overview to see a reference guide on the calculation with descriptions of each row. Select Examples to see how the template could be used in practice.
