Numeric values are usually more than just numbers. They often represent dollar values, dates, percentages, or some other value. You can select the format type that appears as a real value in the Format Cells dialog box. To narrow the list of formats, first select a category in the Category list, then specify the number of decimal places. The default number of decimal places is two.
Excel lets you display numeric values in many ways. Formatting a number means changing the way it is displayed. You can format the number 500 to look like currency, in which case it's displayed as $500.00. You can even specify as many decimal places as you want to display.
You can choose from four currency styles:
Currency with negative numbers preceded by a minus sign
Currency with red negative numbers
Currency with negative numbers enclosed in parentheses
Currency with red negative numbers enclosed in parentheses
Excel's preformatted number formats are listed in Table 9.1.
