JStat and JS floating point errors?

[muh...@gmail.com]

I've tried searching and reading the docs, but don't find anything on this. Does JStat use BigNumber or BigDecimal to handle Javascript floating point errors? We're doing a lot of math where we don't see differences until the 8th or 10th decimal place.

Thanks!

No external libraries are used in jStat. We've been using and modifying algorithms specifically for the numeric precision of javascript's IEEE754 floating point values. This allows for much quicker calculations when you only need around 8 digits of accuracy.

Though there is a case where iterating over the same value can accumulate error. It hasn't been of concern yet, but if it does become a problem I would like to know.
