Why you should switch to 1.9: Three Ruby 1.8 bugs

ruby · ruby1-8 · ruby1-9 · thoughts

Ruby 1.8 dies in June 2012. This post shows some small examples, why this is good ;)

Version used for testing: ruby-1.8.7-p352. Everything works well in 1.9.

>> a=1215449.9999999993
=> 1215450.0 
>> puts "a as Float:   #{a}\na as Integer: #{a.to_i}"
a as Float:   1215450.0
a as Integer: 1215449

>> a = "text with ─ unicode"
=> "text with ─ unicode"
>> a.tr "─", '-'
=> "text with --- unicode"

Not really a bug, but still pretty annoying. You always have to check if the constants exists before using it.
