Decimals
When a cell has the number cell type, you control the
decimal points displayed in the cell from the Format
dialog.
To specify decimal points for the NUMBER cell type:
1. Select a cell or range.
2. Touch FORMAT, then select "Format...."
3. Touch Number.
4. Enter a value between 0 and 15 in the box
beside Decimals.
5. Touch OK.

If you see asterisks (****) displayed across a cell, this
means that the cell is not wide enough to display its
value. To solve this problem, adjust the column width.
(See "Adjusting column and row size" later in this
section.)
NOTE
PenCell uses true values when formulas are calculated
(to at least 15 decimals of precision). The rounded value
appears in the worksheet display, but the true value for
a cell appears in the edit bar when you select the cell.
