It includes over 300 functions for financial, statistical, and mathematical operations, among others. The Scenario Manager provides “what if” analyses. Calc generates 2-D and 3-D charts, which can be integrated into other OOo documents. You can also open and work with Microsoft Excel workbooks and save them in Excel format. Calc can export spreadsheets to Adobe’s PDF and to HTML.
