Ruby/String/Convert to String
Материал из Wiki.crossplatform.ru
call the to_s method on many built-in classes to return the contents of the object as a string
puts 1000.to_s puts [1,2,3].to_s puts ({ :name => "Fred", :age => 10 }).to_s
change the output on the fly with the %s format flag and %:
hi = "Hello, %s" puts hi % "Tom!" # => "Hello, Tom!" puts hi % "people!" # => "Hello, people!" puts hi % "universe!" # => "Hello, universe!"
Convert an object to a string with to_s.
Ruby calls the to_s method from the class of the object, not the String class parentheses are optional. (256.0).class # => Float (256.0).to_s # => "256.0"
