<p class="Paragraph"><help:help-text value="visible">Use this dialog to define the calculation settings for spreadsheets. Define the behavior of spreadsheets with iterative references, the date settings, the number of decimal places and if capitalization or lower cases are to be considered when comparing spreadsheets.</help:help-text></p>
<p class="Paragraph">In this section you may delimit the number of approximation steps carried out during iterative calculations. In addition, you can specify the degree of precision of the answer.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">If you check this box, formulas with iterative references (formula that is continuously repeated until the problem is solved) will be calculated after a specific number of repetitions.</help:help-text> If this box is not checked an iterative reference in the table will cause an error message (this is logical since iterative references normally result from incorrect entered cell references).</p>
<p class="Paragraph">Example:</p>
<p class="Paragraph">You want to divide up a given selling price into the net price and the value-added tax that is contained. You should enter, for example, the text 'Selling price' in A5, enter the text 'Net' in A6, and enter the text 'Value-added tax' in A7. Now enter the selling price (e.g. 100) in B5. The net price should be shown in cell B6 and the value-added tax should be shown in B7. You know that the value-added tax is calculated as 'net price times 15%' and that you arrive at the net price by deducting the value-added tax from the selling price. So you should enter the formula "=B5-B7" in B6 to calculate the net price, and you should enter the formula "=B6*0.15 in cell B7 to calculate the value-added tax. If the iterations are switched off, an error message will appear with the following text in the Status Bar: 'Circular reference'. Switch on the iterations and the formulae will be calculated correctly.</p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Set the maximum number of iteration steps.</help:help-text></p>
<p class="Paragraph"><help:help-text value="visible" xmlns:help="http://openoffice.org/2000/help">Enter the difference between two calculation results into this field. The iteration will be finished if this number is less than the amount specified in this box.</help:help-text></p>
