Calculates the minimum of two numbers.

min(x, y)

x is the first number, any data type y is the second number, any data type

The functions returns the smaller of the two numbers.

sensVal = min(sensVal, 100); // assigns sensVal to the smaller of sensVal or 100
                             // ensuring that it never gets above 100.

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

min(a++, 100);   // avoid this - yields incorrect results

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