+
+max()
+=====
+
+(Macro) Calculates the maximum of two numbers.
+
+Syntax
+------
+
+::
+
+    max(x, y)
+
+Parameters
+----------
+
+**x**: the first number; may be any number or numeric expression.
+
+**y**: the second number; may be any number or numeric expression.
+
+
+Returns
+-------
+
+The larger of the two parameter values.
+
+Example
+-------
+
+::
+
+    sensVal = max(senVal, 20); // assigns sensVal to the larger of sensVal or 20
+                               // (effectively ensuring that it is at least 20)
+
+.. note:: Perhaps counter-intuitively, max() is often used to
+   constrain the lower end of a variable's range, while :ref:`min()
+   <lang-min>` is used to constrain the upper end of the range.
+
+Warning
+-------
+
+Because of the way ``max()`` is implemented, avoid using other
+functions inside the parentheses.  It may lead to incorrect results::
+
+    max(a--, 0);   // avoid this - yields incorrect results
+
+    a--;           // use this instead -
+    max(a, 0);     // keep other operations outside max()
+
+Arduino Compatibility
+---------------------
+
+The Maple version of ``max()`` is compatible with Arduino.
