In Stata, how do I display numeric values with commas inserted?

In Stata, the .format command inserts commas into a large numeric value to make it easier to read. For example, suppose a numeric variable gnp has a value of 12345678.9012, which is 13 characters long (including the decimal point). To insert commas into the numeric value, use this command:

This displays the variable as 12,345,678.9012. The f in the format indicates a real number, while c inserts commas after every three digits, starting from the decimal point and going left. You can also use g to indicate a general, and s to indicate a string. The variable xx in the format %xx.yy should be equal to or longer than the maximum character length of a value, including commas and a period; otherwise, the command will not work.
