Jeremy says in the text that the geometric return is always lower than the arithmetic return unless all the numbers are the same.
杰里米在书里说几何平均,总是比算术平均小,当然如果所有数字都一样,两个均值相等
What we do is we take the interest rate, which I'll call r, and plug it into a formula, which I didn't actually do the arithmetic to their number.
我们只需将利率r,代入等式中,虽然我没有代入数字验证过...
1%10 So if you actually do in a program 11 percent 10, 1 what you'll get back is 1 because that is in fact the remainder of that arithmetic operation.
如果在编程里就是,返回,因为1是这个计算式的余数。
In fact, there are some very old books that show this as the average, the sum divided by two arithmetic mean, but the modern practice is to use the geometric mean.
事实上,一些很老的书籍上,平均的定义就是算数意义的,总的来说被分为两种算数意义,但现代我们多用几何意义。
Or another way of saying it is, we're going to use as the basic steps, those operations that run in constant time, so arithmetic operations.
我们用可以在恒定时间内完成的操作,算法,比较,内存读取。
The truth is after this, it's all arithmetic, right?
真理在这之后,它全是些算术?
