======min(x, y)   ======

====Description   ====

Calculates the minimum of two numbers.

====Parameters   ====

x: the first number, any data type

y: the second number, any data type

====Returns   ====

The smaller of the two numbers.

====Examples   ====
<code arduino>sensVal = min(sensVal, 100); // assigns sensVal to the smaller of sensVal or 100
                             // ensuring that it never gets above 100.</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 min() function is implemented, avoid using other functions inside the brackets, it may lead to incorrect results

<code arduino>
min(a++, 100);   // avoid this - yields incorrect results

a++;
min(a, 100);    // use this instead - keep other math outside the function
</code>
