# `Feel.Value.Null`
[🔗](https://github.com/FeeJai/BDM/blob/feel-v0.1.0/apps/feel/lib/feel/value/null.ex#L1)

The FEEL type `Null`: the bottom of the type lattice (DMN 1.6, sections
10.3.2.1 and 10.3.2.9).

`null` is its only value. It represents missing data and, outside the B-FEEL
dialect, the result of an error. It is represented as `nil`. FEEL has no
"not a number" or infinity values; `null` takes their place.

# `t`

```elixir
@type t() :: nil
```

# `type`

```elixir
@spec type() :: Feel.Type.t()
```

Returns the type descriptor of `Null`.

# `value?`

```elixir
@spec value?(term()) :: boolean()
```

Returns `true` for `nil`.
