Iterative Calculations
Say you make a
mistake, a circular reference that adds itself to itself, then the
computer would calculate the same formula forever. How many
times does Excel repeat a calculation? Once? Twice? You can set the Calculation Options in the Backstage.
Before You Begin: This is an example of a spreadsheet we created in a previous lesson. Any spreadsheet will work for this step.
6. OK, Do This: Find the Calculation Options
Go to
File ->Options->Formulas.
By default, the Workbook Calculation is set on Automatic. There is also an option for Enable iterative calculation. The default settings
are:
Maximum
Iterations: 100
Maximum
Change: 0.001
The
Maximum Change is the smallest change that you will accept between
calculations. The smaller the number, the more accurate the result
and the more time Excel needs to recalculate a worksheet.
