I realized that I didn’t understand exactly how it worked. I mean, I know floating point calculations are inexact, and I know that you can’t exactly represent 0.1 in binary, but: there’s a floating point number that’s closer to 0.3 than 0.30000000000000004! So why do we get the answer 0.30000000000000004?.
