-sq()
-====
-
-(Macro) computes the square of a number.
-
-Syntax
-------
-
-::
-
-    sq(a)
-
-Parameters
-----------
-
-**a**: the number.
-
-Returns
--------
-
-**a** squared (**a** × **a**).
-
-Warning
--------
-
-Because of the way ``sq()`` is implemented, avoid using other
-functions or causing side effects inside the parentheses, as it may
-lead to incorrect results::
-
-    b = sq(a++);   // avoid this - yields incorrect results
-
-    b = sq(a);     // use this instead -
-    a++;           // keep other operations outside sq()
-
-
-Arduino Compatibility
----------------------
-
-Maple's implementation of ``sq()`` is compatible with Arduino.
