Heiler). I can not say much about the reasoning (I am neutral there) but I agree in one regards - if we use a large number, we get all Array members: a = [1,2,3,4] # => [1, 2, 3, 4] a[0..111111111] # => [1, 2, 3, 4] So from this point of view, in this context, infinity could also mean a very large number, in which case the operation should or could be treated like any other high number. But I think matz has to have a look at this since it correlates with the topic of infinity (and to some extent "ranges"; not so much in this example alone necessarily, but I think infinity has to do with ranges as well). ---------------------------------------- Feature #15093: Retrive Array elements with infinite ranges specified by Float::INFINITY https://bugs.ruby-lang.org/issues/15093#change-73955 * Author: v0dro (Sameer Deshmukh) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- Currently in Ruby head (2.6) the following gives an error: ~~~ ruby 2.6-head :001 > a = [1,2,3,4] # => [1, 2, 3, 4] 2.6-head :002 > a[0..Float::INFINITY] #Traceback (most recent call last): # 2: from /home/sameer/.rvm/rubies/ruby-2.6-head/bin/irb:11:in `
' # 1: from (irb):2 #RangeError (float Inf out of range of integer) ~~~ I think `Array` should support infinite ranges created by `Float::INFINITY` as well since `0..nil` and `0..Float::INFINITY` are both supposed to create 'infinite' ranges and having different behavior for each of them is inconsistent. -- https://bugs.ruby-lang.org/ Unsubscribe:
