# High precision calculations in Excel

## Home page

**Enjoy playing with numbers? Do you use Excel?**

I'd like to show you how I've been pushing the precision of calculations much further than is possible with standard worksheet functions.
For example: calculate pi to thousands of decimal places! Mathematicians with access to specialist software can probably do all this very easily.
But why shouldn't those of us using Excel join in with the fun?

If you print the VBA code from these files, I suggest you do so in landscape.

I'd be surprised if you find any of these files "useful" in a practical sense – I don't!
But I have very much enjoyed putting them together. If they spark off an idea of an Excel project you'd like to do,
either chopping some of my code about or starting afresh, I'll feel that this web site has served a purpose.
