3 days agoI bought a cheap scientific calculator for math class. When I tried to multiply .5 by .5 it gave a long irrational number instead of .25. then I had to try to explain to the store clerk why that was wrong before they would accept the return
Weirdly though it wasn’t remotely close to the right answer so I don’t think it was floating point malarkey. I always assumed some defect but I guess we’ll never know.now I wish I had kept it so I could have sent it to Matt Parker for his calculator reviews
