### JSON support
Active Support provides a better implemention of `to_json` than the json gem ordinarily provides for Ruby objects. This is because some classes, like Hash and OrderedHash, needs special handling in order to provide a proper JSON representation.

#### `instance_values`
The method `instance_values` returns a hash that maps instance variable names without "@" to their
corresponding values. Keys are strings:
```ruby
class C
def initialize(x, y)
@x, @y = x, y
end
end
C.new(0, 1).instance_values # => {"x" => 0, "y" => 1}

#### `instance_variable_names`
The method `instance_variable_names` returns an array. Each name includes the "@" sign.

Extensions to `BigDecimal`
--------------------------
### `to_s`
The method `to_s` is aliased to `to_formatted_s`. This provides a convenient way to display a BigDecimal value in floating-point notation:

### `to_formatted_s`
Te method `to_formatted_s` provides a default specifier of "F". This means that a simple call to `to_formatted_s` or `to_s` will result in floating point representation instead of engineering notation:
