Developer’s Description

By PrecisionCalc

Stop letting Microsoft Excel round your numbers to 15 digits.

Get vastly more precise results from mathematical formulas in Excel with xlPrecision, an Add-In for Excel.

Do arithmetic and other numeric analysis on very large numbers without rounding or truncating your numbers to 15 digits, as Excel does on its own. For example, if you add 1234567890 + 0.0123456789, Excel rounds the sum to 1234567890.01235. Get the correct answer in Excel with xlPrecision: 1234567890.0123456789.

Eliminate the stealthy binary conversion errors that plague spreadsheets. Tiny binary conversion errors are common in Excel and other spreadsheets, but do not occur with xlPrecision.

Use much larger (and much smaller) numbers than Excel allows on its own. Excel only understands numbers from about 2.223E-308 to about 1.798E+308. With xlPrecision in Excel, use numbers as tiny as 1.000E-32765 and as huge as about 9.999E+32766.

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

xlPrecision offers many additional features that take you beyond Excel's capabilities in other ways, such as sorting a range of numbers across multiple rows and columns in an array formula, so that it's always correctly sorted with each calculation.

The Free Edition of xlPrecision never expires, and includes all features of the paid editions.

With version 3.1, get faster calculation speed, specify how many decimal places to return with the new format_decimal_place parameter, and conveniently specify the default maximum significant digits in the About box. Version 3.1 also increases the Free Edition to 3,000 significant digits, up from 500 in version 3.0.

Powerful Help, aggressive marketing, impossible to test
bony7April 12, 2009
Pros
At last a calculation in excel, which i s a calculation and not a better estimation. The syntax needs getting used to, especially in complex formulas, it is easy to lose the thread. The price for a medium precision version is moderate.
Cons
For testing this product, one will need a lot of patience. Every use will be checked by a pop-up window, which closing gets more and more complicated. If one is unlucky enough, not to have a satisfying first test - one will never come to an end.
Summary
Promising- Trial ver. is hugely irritating
pboobDecember 8, 2005
Pros
It seems to provide Excel with a minimal capability for high precision calculations. <p>Frequently, the moderate precision of Excel can have crippling effects in technical uses. Round-off in intermediate steps can cause large errors in the final result. This gives a way around the problem.
Cons
Unfortunately, it does not "fix" Excel, just adds a set of text-manipulation functions in addition to the Excel numerical formulas. But, it you wish to integrate the result with other Excel formulas, you have to be pretty sharp with conversions. <p> <p>And the huge thing (I gave up after about 23 minutes and 12.6549 seconds) is the popups. Every time you use one of the new formulas, you get a recommendation to buy. This would not be too bad, but after a few formulas, it dosent just need an OK, but starts to ask for confirmation codes, like "type xyz to use the formula" and every time, the key gets longer! It claims that it starts over when Excel is restarted, but by that time I was cranky and uninstalled it. <p> <p>Oh, and it does not have a high-precision "random" function. <p> <p>The price to buy sounds reasonible, but I dont have enough need to put up with the irritating trial to see if it is really better than other apps that give high precision.
