.. highlight:: cpp
.. _lang-highbyte:
highByte()
==========
(Macro) Extracts the second lowest byte of an integral data type.
.. warning:: This macro is provided for compatibility with Arduino
only. It returns the second-least significant byte in an integral
value. It makes sense to call this the "high" byte on a 16-bit
``int`` microcontroller like the Atmel chips on Arduinos, but it
makes no sense at all on a 32-bit microcontroller like the STM32s
in the Maple line.
In short: we provide this so that existing Arduino code works as
expected, but **strongly discourage its use** in new programs.
Syntax
------
::
highByte(x)
Parameters
----------
**x**: a value of any integral type.
Returns
-------
Second lowest byte in **x**.
Example
-------
::
int x = 0xDEADBEEF;
SerialUSB.println(x, HEX); // prints "BE"
Arduino Compatibility
---------------------
The Maple version of ``highByte()`` is compatible with Arduino.
