    • The "solution" to the (non-)error is to ignore it, and ensure that you use an appropriate function, ie toFixed(n) , to present the number with the desired number of decimal places.

    It's important to know the difference between the internal representation of a value, and how to present that value to the end user.

    您可以使用https://github.com/ekg/fraction.js库获取中间值，并将最终结果转换回十进制值以最大限度地减少错误。
