Bug #21175
Updated by andrykonchin (Andrew Konchin) 5 days ago
I would expect that for a Range with Integer right boundary `end - 1` is returned: ```ruby (nil...10).max # => (irb):1:in 'Range#max': cannot exclude end value with non Integer begin value (TypeError) ``` `#max` works well with non-nil `begin`: `self.begin`: ```ruby (1...10).max # => 9 ``` Related issue - https://bugs.ruby-lang.org/issues/17034
