Nothing surprising... There is a limit to the precision, possibly even for the computer... After all, it's no secret that 0.(9) = 1. Any schoolchild knows that...

That's why I've always considered rounding up to be more correct for myself. For example, if the number 0.459 needs to be rounded to an integer, it should result in 1, not 0 :) Although, according to the rules, it turns out to be some kind of nonsense. After rounding, it can be either 0 or 1 :) depending on which rounding rule is used :) And the computer, it seems, first calculates the rounding using the rule with deficiency and gets 0, and when there are not enough
