Format string
Use a format string to format the data displayed in the query. First, select the format type. Then, type a format string to modify the format type you selected. The valid options depend on the format type you select. A format string must begin with a % sign and end with a format type character:
[%] [type]
If required, you can also include:
- An argument index specifier. See Argument index specifier
 - A left justification indicator. See Left Justification Indicator
 - A width specifier. See Width specifier
 - A precision specifier. See Precision Specifier
 
[%] [index:] [-] [width] [.precision] [type]
To specify how many decimals to use in a format string, set the format string to the normal format you can use. Add the precision specifier a decimal point and the number of digits to follow it before the format string character but after the initial %. For example:
- Field Type: Float
 - Format Type: ftCurrency.
 - Format String: %.4f
 - Data (Unformatted): 3.1415926&ldots;
 - Result: 3.1416
