I'm not OP, but my guess is they're referring to the Intel math bug that some i5's had. I'm struggling to track it down, but it's basically an issue with doing long division where the floating point math would produce a very wrong result.

You can see more here at least for the bug/issue that existed in the 90's here

I’m not actually, just that a binary integer that overflows at 60 couldn’t exist, hence the 5.907 whatever bit length

oh, that's actually clever. And I'm saying that as a software engineer. I missed that possibility :)

I should have phrased it differently, like “Ah yes, the well known 5.9068905956 bit integer.” But thanks
