In Microsoft Excel, the appearance of a number is separate from the number that is stored in the cell. For example, a number may be displayed as rounded when its number of decimal places is too small or when the column isn't wide enough to display the number. Calculations that include the rounded number, however, will use the entire number that is stored behind the display.
To stop numbers from being displayed as rounded, you can increase the number of decimal places for that number, or you can increase the column width.
