Editing Extras Calculator
There are a number of options on the extras [icon--app-more] menu. All of these options are available while editing a template except where noted.
Inserting & Deleting Rows
By default, PowerOne adds new rows to the bottom of the template. It is, however, possible to insert rows elsewhere. Select the desired row then [icon--app-more | extras menu] then **Insert Row** to insert a row above the selected row.
It is also possible to remove undesired rows. Select the row you wish to delete then [icon--app-more | extras menu] then **Delete Row**. Note that there is no confirmation and no method to recover from row deletion without recreating it.
There are various special characters used with variables, units and text rows. For instance starting a line with an exclamation mark creates a headline such as this section contains. On iOS, select **symbols** in the editor or on the web select [icon--app-more | extras menu] then **Insert Formatting** for a list of various options.
In particular, ², ³, and ° are all available there for creating area, volume and temperature units, respectively. In addition, the constant π is available for using its value in equations. On iOS, standard math symbols are also available. Finally, there are many text formatting options available.
On iOS tap [icon--app-more | extras menu] then **Advanced** then **Duplicate** to make a copy of a template. On the web select [icon--app-more | extras menu] then **Duplicate** to make a copy of a template. Once duplicated you can edit the template without modifying the original.
This option is available on iOS only while using a template and available both when using and editing a template on the web.
View Calculation Log
Sometimes it is not clear why a template is misbehaving. In these cases, it is often useful to see how PowerOne's engine viewed your template. The Calculation Log shows you exactly how PowerOne engine works, stepping you through how the template calculates using many of the concepts discussed above.
To see the calculation log on iOS, tap [icon--app-more | extras menu] then **Advanced** then **View Calculation Log** while using the template. On the web tap [icon--app-more | extras menu] then **View Calculation Log** while editing the template.

The calculation log is updated after each calculation (including Clear), displaying each equation, in the order it was considered, and the decisions it made. Separators separate unique calculation events with the most recent at the bottom.
It retains up to 100 events and can be cleared (via Clear Log). We even provide a simple method to email technical support to get help with your template and share with us your log.
It is often handy to see what another template author did with their templates, especially those in the [https://.../library | library].
When using a template, the option to **View Source** appears on the [icon--app-more | extras] menu. On iOS tap **Advanced** within the [icon--app-more | extras] menu. Select this option to review the source for any template. Tap variables and equations to review their details.
Additional settings are available while editing a template. Not only do you still see Decimals, Inches and Text Size, but you also see options for customizing search, setting default tags and creating template collections:
- ++**Decimals**++: Sometimes it is helpful to view a different number of places than those designated by the author. This setting changes the decimal places displayed for all number values in the template.
- ++**Inches**++: Sometimes it is helpful to view feet-inch results in different fractional inches than those designated by the author. This setting changes the fractional inch displayed for all feet-inch values in the template. Internally the denominator adjusts to the selection, the numerator is rounded and finally the entire fraction is reduced.
- ++**Text Size**++: On the web, PowerOne can display the template in four different sizes: small, medium, large, or extra large. On iOS the size is determined by your Dynamic Type setting (Settings then Display & Brightness then Text Size).
- ++**Title**++: On iOS, change the title via this setting. On the web, change the title by selecting it and modifying within the navigation bar.
- ++**Case Sensitive Variables**++: check this option to make sure variables are treated as case sensitive. By default, PowerOne assumes variable 'g' and variable 'G' are the same. This option treats them as two separate variables instead.
- ++**Solve Equations**++: By default, PowerOne assumes that everything left of the equals sign is a single variable. Sometimes, though, you use math on that side of the equation. Turn this option on to enable that instead. Note that if PowerOne finds a variable that matches the left side of your equation it will still treat it as a single variable. Delete any matching variables before re-entering the equation if needed.
- ++**Icon**++: Choose an icon that appears next to the template name in the list.
- ++**Search Keywords**++: PowerOne automatically includes the template title and variables as search terms. Add additional search words or phrases here, one per line. For instance, Time Value of Money's variables include Present Value and Future Value but buttons on hardware calculators include the abbreviations PV and FV, which were added to the Search Keywords list.
- ++**Default Tags**++: When sharing templates, it is often nice to offer a default set of tags in which to add to the follower's account. This helps with organization without requiring the follower to create his own. This set of tags can be different from those tags you set for yourself. And as noted these are a default. The follower can modify his list of tags without impacting yours or the original defaults. These default tags work the same as tags do in so much as you add them one per line.
