Example

In the "Monthly Statewide Seasonally Adjusted Unemployment Statistics" table (pub.fin.fred2.bls.smsa), you can create a computed column that displays the number of characters of the values in the unemp_rate column:

<base table="pub.fin.fred2.bls.smsa"/>
<willbe name="example" value="width(unemp_rate)" label="Width of`Rate"/>

For a value of 6.6, the result would be "3".

For a value of 11.0, the result would be "2".

You can create a computed column that displays the number of characters of the values in the month column:

<willbe name="month_example" value="width(month)" label="Width of`Month"/>

For a value of 01/76, the result would be "6" because the value of the underlying integer in <month> form is 197601, which is 6 characters in length. It is displayed as 01/76 in the table because of the display format applied to the month column.

Additional Information

This function does not work with Unicode (UTF-8) strings.
