Ah, I see you've worked on financial software as well ;) We've definitely had our fair share of "IDK what to tell you, those guys are mathing wrong". TBF, tho

Ah, I see you've worked on financial software as well ;) We've definitely had our fair share of "IDK what to tell you, those guys are mathing wrong". TBF, though, most customers are pretty tolerant of explainable differences in computed values. There's a bunch of "meh, close enough" in finance. We usually only run into the problem when someone (IMO) is looking for a reason not to buy our software. "It's not a perfect match, no way we can use this" sort of thing.
