+
+byte() (cast)
+=============
+
+Converts a value to the :ref:`byte <lang-byte>` data type.
+
+.. note::
+
+ Casting to the byte type is provided for compatibility with
+ Arduino. However, the recommended Maple type for storing an 8-bit
+ unsigned integer is ``uint8``. (C and C++ programmers: ``stdint.h``
+ is also available).
+
+ In order to cast a variable ``x`` to a ``uint8``, the
+ following syntax can be used::
+
+ uint8(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.
