Abstract
Cells containing either numeric value or formula whose result is numeric are subject to automatic adjustment of decimal places based on the available column width. The automatic decimal place adjustment takes place only when their number format is General.

Detailed Specification
Options dialog
In the Options dialog, the Calculate page will have a new check box labeled Limit decimals for general number format. When this check box is checked, you can specify the maximum number of decimal places allowed for cells with General number format. A value of 0 to 20 is allowed as the maximum number of decimal places.
When this check box is not checked, cells with General number format will use as many decimal places as the column width allows. By default, this option is not checked.
Adjusting decimal places by column width
When the number format for a cell is General and its displayed value is numeric, it undergoes automatic decimal place adjustment to fit available column width if the column is not wide enough to display the cell value in full. This adjustment is performed in the following fashion.
First, Calc tries to fit the displayed number within the width of the cell by reducing the number of decimal places. If the number doesn't fit even after all the decimal places have been exhausted, it then switches to scientific notation and continue adjusting decimal places in that notation. If the number still doesn't fit even with the scientific notation, it displays '###' in place of the original value.
Handling of small numbers
There is an exception to this rule specified above. When the value of the cell is less than 0.0001 (=1.0E-04), the value is displayed in scientific notation if
- the total number of characters to be displayed in decimal notation exceeds 11 (or 12 for negative numbers accounting for the minus sign) even if the column is wide enough to display it without automatic adjustment, or
- the value is undergoing automatic adjustment to fit the column width.

Configuration
The node Calc/Calculate/Other/DecimalPlaces stores The option for the automatic adjustment of decimal places for the General number format. When the Limit decimals for general number format option is not set, the value of -1 is stored in this node. When this option is set, the specified decimal places (which is a positive value) is stored in this node instead.
