+.. _lang-doublecast:
+
+``double()`` (cast)
+===================
+
+Converts a value to the :ref:`double <lang-double>` floating point
+data type. Here is an example::
+
+ int x = 2;
+ double d = double(x); // d now holds 2.0, a double value
+
+The value ``x`` can be of any type. However, if ``x`` is not a number
+(like an ``int`` or ``long``), you will get strange results.
+
+See the :ref:`double <lang-double>` reference for details about the
+precision and limitations of ``double`` values on the Maple.
