Get Your Numbers Right
xlPrecision 2.0 Free Edition
The Free Edition of xlPrecision 2.0 includes all the features of all the paid editions, but is limited to 150 significant digits. That's still 10 times as much precision as you get in Excel without xlPrecision!
You may use the Free Edition as much as you wish, for as long as you wish, and on as many computers as you wish. There are no restrictions. You may freely distribute the Free Edition to anyone you wish.
However, each time an xlPrecision function calculates, a dialog will appear. You must click OK on the dialog for xlPrecision to return its result. Every fifth of these dialogs will present you with a random text string that must be typed in before the OK button becomes enabled. The random text strings start out 3 characters long, and grow by 1 character with each string, up to 25 characters. If you cancel one of the dialogs that ask for a text string, the next calculation skips to the next dialog that asks for a text string. To start over at 3 characters, you must restart Excel. To avoid these dialogs, simply buy a paid edition.
This ensures that you have as much time as you desire to fully evaluate the product before making a purchase decision, while providing a pragmatic disincentive to perpetual freeloading. And if you use the product only very rarely, or have more time than money, you can enjoy a great product free of charge, without being nagged or made to feel guilty.
A different Free Edition, with 2,147,483,648 (over two billion) significant digits, is also available, but it is more restrictive than the standard, 150 SD edition above. The 2,147,483,648 SD Free Edition requires a random text string that must be typed in every calculation instead of every 5th calculation, and the random text strings start at 20 characters instead of 3. Also, it is intended for use in your programming code rather than within Excel worksheets, as it can return more characters than Excel can accept in a worksheet cell.
