  nil.to_i is defined

 false.to_i is not defined

  Well, first ruby look if #to_ary exist and call it otherwise it try to
  call #to_a

N>  Integer(foo) != foo.to_i
N>  Float(foo)   != foo.to_f

 it depend of foo

pigeon% ruby
class A
   def to_f
      12.0
   end
end

p Float(A.new)
^D
12.0
pigeon%
