.. _arduino-bytecast:
byte() (cast)
=============
Description
-----------
Converts a value to the :ref:`byte <arduino-byte>` data type.
.. warning::
Casting to the byte type is provided for compatibility with
Arduino. However, ``byte`` is a non-standard type. The standard
C++ type for storing an 8-bit unsigned integer is ``unsigned
char``, and we recommend using that instead.
In order to cast a variable ``x`` to an ``unsigned char``, the
following syntax can be used::
(unsigned char)(x);
Syntax
------
``byte(x)``
Parameters
----------
**x**: a value of any integer type
Returns
-------
The value, converted to a ``byte``. Note, however, that if the value
is larger than the maximum value you can store in a byte (255), then
the results might be strange and unexpected.
