+
+double() (cast)
+===============
+
+Description
+-----------
+
+Converts a value to the :ref:`double <arduino-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 <arduino-double>` reference for details about the
+precision and limitations of ``double`` values on the Maple.
