Won’t that make reproducing results difficult? I mean it seems like a result won’t be worth much if it’s only reproducable with a specific version of say glibc from five years ago.

Over the cause of one experiment sure, I can see why you’d like to know the calculation are done identically. I just question the validity/usefulness of a calculation that can only be repeated on one version of some library. Surely the overall result should remain the same.

There are always inconsistencies in the scientific world:

A good portion of experimentalists' time is probably spent in trying to figure just how badly they've messed their experiments as compared to reality. Major discoveries are sometimes based on teasing apart those differences:

In my EE studies we had a specific course just in examining the limitations of (digital) numbers:
