That seems pretty uncommon to me. I could contrive a few examples that aren't totally outlandish (say you're scaling/normalizing a value by groups, you might save the log base that you did the normalization with to be able to transform something back into the original values. But that's pretty contrived, and I bet most people would approach that with a lookup table and a for loop, basically. -- This is an automated message from the Apache Git Service.
