relative error

基本解释

That's very small-- that's what we call the relative error.
非常小,我们称其为相对误差。
Often what you should test is the relative error in terms of ULPs.
通常，就 ULP 进行测试时考虑的是相对错误。
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.
并不是,测量一个周期，而是，测量10个周期，因为这样,不确定性减小，测量值的,相对误差减小。

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.

相对误差
Through many tests, the relative error of correlation matrix between the results of our design and MATLAB program is better than 6‰.
通过实际测试,相关矩阵的计算结果与双精度浮点的相比,相对误差在2‰～6‰之间。

相对误差
The depth relative error was 1%, and width error was 10%, spot size was 130um.
测试结果是深度相对误差为1%,而线宽相对误差为10%。实测光斑为130um左右。
