-``long long``
-=============
-
-The ``long long`` data type stores extended size integer values. You
-can use a ``long long`` when your values are too large to fit into an
-:ref:`int <lang-int>`. A ``long long`` occupies 8 bytes of memory.
-This yields a range of approximately -9.2×10^18 to 9.2×10^18 (that's
-9.2 billion billion, or about 92 million times the number of stars in
-the Milky Way galaxy). The exact range of a ``long long`` on the
-Maple is from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807,
-or -2^63 to (2^63-1). A ``long long`` it is subject to the same
-:ref:`overflow issues <lang-variables-rollover>` as any numeric data
-type.
-
-A synonym for the ``long long`` type is ``int64``.
-
-Here's an example of declaring a long long (see :ref:`integer
-constants <lang-constants-integers-u-l>` for an explanation of the
-"LL" at the end of the number)::
-
- // Speed of light in nanometers per second (approximate).
- long long c = 299792458000000000LL;
-
-The general syntax for declaring an ``long long`` variable named ``var``,
-then giving it value ``val``, looks like::
-
- long long var = val;
-
-This is identical to the ``int`` syntax, with ``long long`` (or, at
-your option, ``int64``) replacing ``int``.
-
-Note that ``long long`` values will still :ref:`overflow
-<lang-int-overflow>`, just like ``int`` values, but their much larger
-range makes this less likely to happen.
-
-The downside to using a ``long long`` instead of an ``int`` (besides
-the extra storage) is that :ref:`arithmetic <lang-arithmetic>`
-operations on ``long long``\ s will take slightly longer than on
-``int``\ s.
