.. _arduino-min:
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
--------
::
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
