I can’t speak for low battery, but I can for different brands of calcs.
Back in high school majority of students had this specific model, and I had a different one. My entire answer to a question on an exam was correct, but my calculator somehow calculated different decimals to the ones from the popular model. And it was like 4th, 5th decimal or something. The asshole teacher took all of my points away on that. Meanwhile, one of her fave students forgot a very important part of the formula which made the calculation completely wrong and the teacher still gave them half the points for it. God, I hated school, lol.
Wait, it gets things wrong on low battery?
It…shouldn’t. The 7-segment displays will have contrast issues, then the whole thing will stop working entirely when the battery gets too low.
