The Percent data type is like the Number data type, but for percentages of numbers. Currency data types have custom formatting options and accept numeric characters, but are shown with the % symbol and calculated as percentages in formula.
Like other number types, you can convert existing data (for instance fractions and decimals) to the Percent data type (for instance 0.5 to 50%). Setting your cells and columns as the percent data type is helpful for differentiating those numbers you think of in terms of percentage, like interest rates, discounts, or how complete this sentence is (100%).
Like other data types, Percent data types can have Strict enabled. Selecting the Strict checkbox for Percent cells will restrict users to input only numeric characters. Percent data types will convert any numerical entry to a percentage, for instance, typing "5" results in and typing "0.5" results in . Also, columns that have Strict enabled cannot have cells of different data types.
Note: Currently, formulas are not allowed in Strict Percent cells. When there are existing formulas in a column, cell, or range of cells and you change to strict, those formulas will be converted to the output value. You can always revert by selecting undo in the toolbar or with the keyboard shortcut Ctrl + Z (CMD + Z for Mac users).
With the Percent data type, you can select how many decimal places to show. Like other spreadsheets, Spreadsheet.com defaults to 2 and does not delete any numerals not shown, simply hides them. Defaulting to percent data like this: .
The Format drop-down at the bottom of the update dialog window allows you to customize which characters you use for formatting, for instance choosing a comma or period as the 1000 separator. This is helpful to format for different countries or style preferences.
