I am not objecting to the functionality; I'm objecting to bolting on ad-hoc operators one at a time. I think an expression syntax would let us do this in a much more scalable way. If I had time, I'd go do that, but I don't. We could add abs(x) and hash(x) and it would all be grand.
Ok. I do agree that an expression syntax would be great!
Yes, it's not bad.
However, will we need some method of modulo calculation?
I don't think so much. I think most intuitive modulo calculation method is floor modulo,
Because if we use the negative value in modulo calculation, it just set negative value as both positive values,
it is easy to expect the result than others. This strong point is good for benchmark script users.
But I don't have any strong opinion about this patch, not blocking:)
