I’d like to raise your attention to this issue that appeared in CMSSW:
1 commits changed 1 files with 20 additions and 15 deletions .
Questions for the ROOT team are:
- Was this behaviour recently changed? I could browse the history myself, but maybe somebody remembers.
- Shouldn’t TMath::AreEqualAbs use a less-than-or-equal comparison, so that
epsilon=0can still succeed?
- Any suggestions on how to check the compatibility of histograms for add/merge? Catching the exception is sort-of ok, but discouraged; the helpers like
CheckConsistencyare not public.
