+======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>
