Sphygmic Software Spreadsheet gives you all the spreadsheet functions you need in less than 4MB -- for free! It offers 125 built-in functions, along with full-featured math capability for statistical, financial, and date/time calculations. The worksheets span 256 columns and 16K rows, so you won't find yourself restricted for space. Formatting supports color, fonts, text size, currency, and justification options, as expected. Graphing is available by simply selecting the cells containing the data points. Online help is sparse, however, with only two pages listing the functions and operators. Still, how much more do you want for free?
