+The built-in ``QlBuiltins`` module provides a type ``BigInt`` of arbitrary-range integers.
 
 Unlike ``int`` and ``float``, there is no automatic conversion between ``BigInt`` and other numeric types.
 Instead, big integers can be constructed using the ``.toBigInt()`` methods of ``int`` and ``string``.

 QL has a range of built-in operations defined on primitive types. These are available by using dispatch on expressions of the appropriate type. For example, ``1.toString()`` is the string representation of the integer constant ``1``. For a full list of built-in operations available in QL, see the
 section on `built-ins <https://codeql.github.com/docs/ql-language-reference/ql-language-specification/#built-ins>`__ in the QL language specification.
