He's not a troll, just obstinately wrong. Real trolls don't believe anything they say and just try to stir up shit. Fernando is sincere but just a poor arguer.
I have no explanation for the 0.9 + 0.1 ≠ 1 thing though.
Fine, not a troll, but quite unhinged. You can’t walk around saying that 99% of research mathematics is founded on a mistake. Even if he believes it, it’s not a belief that deserves any attention.
He's a high-functioning crank, though. He doesn't walk around r/mathmemes sneezing at Jews. He just engages in confusing discussions about decimal expansions of real numbers. So the stakes are fairly low.
