Calculates the maximum of two numbers.
x is the first number, any data type
y is the second number, any data type
The functions returns the larger of the two numbers.
// EXAMPLE USAGE sensVal = max(senVal, 20); // assigns sensVal to the larger of sensVal or 20 // (effectively ensuring that it is at least 20)
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
max(a--, 0); // avoid this - yields incorrect results a--; // use this instead - max(a, 0); // keep other math outside the function
