Infinity -- Float

It seems that Ruby has a concept of infinity:

Quote:

>> 1.0/0
=> Infinity
>> (1.0/0).class

=> Float

I wish to return this value, but I can't quite figure out what Ruby's
symbol for Infinity is. I guess that I could write:

my_method
...
return 1.0/0
end

But I'd rather do something like

my_method
...
return Infinity
end

(Replace "Infinity" by the appropriate value).

Does anyone know what symbol Ruby uses for "Infinity"?
