Calculates the minimum of two numbers.
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.
// EXAMPLE USAGE 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 a++; min(a, 100); // use this instead - keep other math outside the function
