raymondtay commented on issue #868: [SYSTEMML-2537] Improve the consistency of predicates in "if-then-else" expressions URL: https://github.com/apache/systemml/pull/868#issuecomment-604192818 > thanks for creating the issue, but I'm afraid that DML follows R semantics here where both if conditions and ifelse functions interpret negative values as TRUE. Do you think adding this to the docu would help. > > Btw, in the next days we'll merge SystemDS back into Apache SystemML with many new features and a packed roadmap. I think adding the documentation to SystemML would definitely clarify the issue. Thank you for enlightening me on this fact w.r.t **R programing language**.
