Hey @mjhasbach I received this error as well on my local (a few tests w/in stats failed actually) but Travis is still reporting all green: https://travis-ci.org/numbers/numbers.js

There's an acceptable "error bound" for operations in numbers, numbers.EPSILON = 0.001. Given that this mismatch is within that range, it's ok. Need to update the tests to accommodate for that.
