Stop letting Excel round your numbers to 15 digits! Get full precision now!

Work with very large numbers in Microsoft Excel without them being automatically rounded. Get full precision up to 32,767 digits.

xlPrecision is an Add-In for Microsoft Excel that provides vastly more precise results from mathematical formulas than Excel provides on its own. xlPrecision allows you to do arithmetic and other work on very large numbers without rounding or truncating your numbers. Don't be held back by Excel's limitation of only 15 significant digits!

xlPrecision also eliminates the stealty binary conversion errors that hide undetected until suddenly making a spreadsheet give an incorrect result.

xlPrecision also empowers you to use much larger (and much smaller) numbers than Excel allows on its own. With xlPrecision, you can use gigantic numbers with over 106 TIMES as many digits as Excel allows, as well as extremely tiny numbers with over 106 times as many zeroes to the right of the decimal.

If you're a programmer, xlPrecision's arbitrary-precision (bignum, multi-precision) arithmetic library functions can be called directly from your own programming code.

If you're a number theory mathematician, you'll enjoy the 2,147,483,648 significant digits (yes, over two billion!) available in a special version of xlPrecision made at the request of a number theorist at a German university.

xlPrecision offers many additional features that take you beyond Excel's capabilities in other ways. Save valuable time with xlPrecision's powerful Excluder functions. View your sorted data at a glance with the exceptional sorting function. Take control of your fractional data with the versatile fraction reducer.
