# ASC Function

The ASC function is one of the text and data functions. Is used to change full-width (double-byte) characters to half-width (single-byte) characters for languages that use the double-byte character set (DBCS) like Japanese, Chinese, Korean etc.

The ASC function syntax is:

ASC(text)

where text is a data entered manually or included into the cell you make reference to. If the text does not contain full-width characters it remains unchanged.

To apply the ASC function,

1. select the cell where you wish to display the result,
2. click the Insert function icon situated at the top toolbar,
   or right-click within a selected cell and select the Insert Function option from the menu,
   or click the icon situated at the formula bar,
3. select the Text and data function group from the list,
4. click the ASC function,
5. enter the required argument,
6. press the Enter button.

The result will be displayed in the selected cell.
