INFO: Format Function and International Settings

MORE INFORMATION

A common use of the Format function is to format numbers for a consistent display. To do this, two parameters are passed to Format. The first parameter is any valid numeric expression, such as 5555.5, "5555.5," etc. The second parameter is a format expression, such as "###,###.00."

The key point of emphasis is this: if the first parameter is a string representation of a number, such as "5555.5," Format expects it to be in the proper regional setting as portrayed in Control Panel / Regional Settings. However, Format always expects the second parameter to be in the "English (United States)" setting.

For example, if the regional setting is such that the decimal symbol is "," and the digit grouping symbol is ".", the following will occur: With the regional setting as described above, the number 5555.5 and the string "5555.5" are interpreted quite differently by Format.
