Floatingpoint Numbers are not exact, and manipulating them will result in rounding errors.
浮点数不是精确值,所以使用它们会导致舍入误差。

As a result, floatingpoint operations may result in rounding errors, yielding a result that is close to — but not equal to — the result you might expect.
因此,浮点运算可能导致舍入误差,产生的结果接近—但不等于—您可能希望的结果。
