relative error

基本解釋

That's very small-- that's what we call the relative error.
非常小,我們稱其爲(wèi)相對(duì)誤差。
Often what you should test is the relative error in terms of ULPs.
通常，就 ULP 進(jìn)行測(cè)試時(shí)考慮的是相對(duì)錯(cuò)誤。
But instead of measuring one period, I'm going to measure ten periods, because that gives me a smaller uncertainty, a smaller relative error in my measurements.
竝不是,測(cè)量一個(gè)周期，而是，測(cè)量10個(gè)周期，因爲(wèi)這樣,不確定性減小，測(cè)量值的,相對(duì)誤差減小。

However, as index-based mutual funds and ETFs continue to gain popularity and active managers are increasingly pressured to control their performance tracking error relative to benchmark indexes, the markets could become less efficient.
