We need to be accurate to two decimal places (e.g. in a simple accounting package), scale everything up by 100, and convert it back to floating point as late as possible.

我们处理小数的时候要精心些，比方说我们在做一个简单的统计程序时，要限制结果不能超过100，要尽可能晚的把它转化成浮点数。

If you actually want to count the number of decimals, you'd probably have to convert to a string, remove any trailing zeroes, and see where the decimal point landed.

如果你真的要数小数点后的位数，你可能要转换为字符串，删除任何尾随零，看看小数点落在哪里。
