======max(x, y)   ======

====Description   ====

Calculates the maximum of two numbers.

====Parameters   ====

x: the first number, any data type

y: the second number, any data type

====Returns   ====

The larger of the two parameter values.

====Example   ====
<code arduino>sensVal = max(senVal, 20); // assigns sensVal to the larger of sensVal or 20
                           // (effectively ensuring that it is at least 20)</code>
====Note   ====
Perhaps counter-intuitively, max() is often used to constrain the lower end of a variable's range, while min() is used to constrain the upper end of the range.

====Warning   ====
Because of the way the max() function is implemented, avoid using other functions inside the brackets, it may lead to incorrect results

<code arduino>
max(a--, 0);   // avoid this - yields incorrect results

a--;           // use this instead -
max(a, 0);     // keep other math outside the function
</code>
