.. _arduino-abs:
abs(x)
======
Description
-----------
(Macro) computes the absolute value of a number.
Parameters
----------
**x**: the number.
Returns
-------
**x**: if **x** is greater than or equal to 0.
**-x**: if **x** is less than 0.
Warning
-------
Because of the way ``abs()`` is implemented, avoid using other
functions or causing side effects inside the parentheses, as it may
lead to incorrect results::
abs(a++); // avoid this - yields incorrect results
abs(a); // use this instead -
a++; // keep other operations outside abs()
Arduino Compatibility
---------------------
Maple's implementation of ``abs()`` is compatible with Arduino.
