Bug #15518
Updated by sakuro (Sakuro OZAWA) almost 6 years ago
Ruby 2.5.3's behavior
~~~
# without step, it produces integer sequence
>> (1..Float::INFINITY).first(10) #=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
# with step, it produces floats instead of integers
>> (1..Float::INFINITY).step(1).first(10) #=> [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0]
~~~
Ruby 2.6.0's behavior
~~~
# endless range
(1..).first(10) #=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
# with step, all numbers are integer now
(1..).step(1).first(10) #=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
# old idiom with Float::INFINITY
(1..Float::INFINITY).first(10) #=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
(1..Float::INFINITY).step(10).first(10) #=> FloatDomainError (Infinity)
