Ruby: type() global method

I'm just curious what the type() global method is.

I used it

a = 1
puts type(a)

and just go开发者_开发知识库t "wrong number of arguments (1 for 0)".

It’s a deprecated equivalent of class, and it’s gone in 1.9.

>> send :class
=> Object
>> 1.type
(irb):5: warning: Object#type is deprecated; use Object#class
=> Fixnum

Deprecated synonym for Object#class.
