How to calculate with more precision

[Olaf Doschke]

I just posted faq184-7862

At the end of thread184-1738764 I said I work on a string math library, that took a while because it wasn't main focus and also I needed a bit more debugging on the divide operation.

The last sample of the FAQ code covers the famous case of thread184-1738661.

I'd be glad, if you stress test this and find bugs. If it's somehow useful to you, still be cautious it doesn't come with a warranty. You might contact me for generating a more stable lib with perhaps more functionality and performance tuning, too.

Bye, Olaf.

Interesting library. Thank you for sharing.

Thank you.

It already offers many more methods, even trigonometrical functions.

I'll see, if I combine this with my ideas. He uses strings like I do, but during calculations digits are represented by array elements, good thought at least for more complex calculations, that process the same number multiple times it can pay to split the string into an array and finally combine the array to a string.

This library is from 2002 and since the 65000 element limitation of arrays was dropped in VFP9 it can handle even larger numbers today without any change.

Bye, Olaf.
