.. _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 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.
