<p class='vspace'></p><h2>min(x, y)</h2>
<h4>Description</h4>
<p>Calculates the minimum of two numbers.
</p>
<p class='vspace'></p><h4>Parameters</h4>
<p>x: the first number, any data type
</p>
<p class='vspace'></p><p>y: the second number, any data type
</p>
<p class='vspace'></p><h4>Returns</h4>
<p>The smaller of the two numbers.
</p>
<p class='vspace'></p><h4>Examples</h4>
<pre>sensVal = min(sensVal, 100); // assigns sensVal to the smaller of sensVal or 100
                             // ensuring that it never gets above 100.
</pre><h4>Note</h4>
<p>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.
</p>
<p class='vspace'></p><h4>Warning</h4>
<p>Because of the way the min() function is implemented, avoid using other functions inside the brackets, it may lead to incorrect results
</p>
<p class='vspace'></p><pre>
min(a++, 100);   // avoid this - yields incorrect results

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

</pre>
