doubles do better because they have more bits (which is one reason you should almost always use doubles instead of floats); but there are still practical limits to how accurate they can be.

使用 double 数会更好，因为它们的位数更多（这是应该总是使用 double 数而不是 float 数的理由之一）；但它们的精度仍然受到一定限制。

But they're not accurate all the time in predicting bonding within molecules, and the reason for this is because Lewis structures are not, in fact, based on quantum mechanics.

但它们在预测分子内，成键时不总是正确的，这是因为Lewis结构，实际上不是基于量子力学的。

Accurate, at least in the spring and fall, but the reason it works is more complicated than we might initially think.

至少在春季和秋季是准确的。

Admittedly, we were right for the wrong reason, but nonetheless, we believe that we deserve the full 20 points for this highly accurate prediction.
