-.. function:: abs(number, /)
+.. _function:: abs(number, /)
 
    Return the absolute value of a number.  The argument may be an
    integer, a floating-point number, or an object implementing
    :meth:`~object.__abs__`.
    If the argument is a complex number, its magnitude is returned.

    Return an :term:`asynchronous iterator` for an :term:`asynchronous iterable`.
    Equivalent to calling ``x.__aiter__()``.
