[Gretl-users] Data format

Hello I have imported data from Excel into Gretl. Numbers like 90454.8169 are displayed in Gretl without decimal places. When I go to display values and chose select data format with 4 decimal places the same numbers are displayed as in Excel. This format does not remain. When I display the data again the round numbers appear. How can I have the data in Gretl with 4 decimal places? Thank you for your help Raul Gimeno
