Description
Calculates the maximum of two numbers.
Syntax
max(x, y)
Parameters
x: the first number, any data type
y: the second number, any data type
Returns
The larger of the two parameter values.
Calculates the maximum of two numbers.
max(x, y)
x: the first number, any data type
y: the second number, any data type
The larger of the two parameter values.
The code ensures that sensVal is at least 20.
sensVal = max(senVal, 20); // assigns sensVal to the larger of sensVal or 20
// (effectively ensuring that it is at least 20)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.
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
max(a, 0); // use this instead -
a--; // keep other math outside the function
