<h2 id="Summary" name="Summary">Summary</h2>
<p>The <strong><code>Number.MAX_VALUE</code></strong> property represents the maximum numeric value representable in JavaScript.</p>

<div>{{js_property_attributes(0, 0, 0)}}</div>

<h2 id="Description" name="Description">Description</h2>
<p>The <code>MAX_VALUE</code> property has a value of approximately <code>1.79E+308</code>. Values larger than <code>MAX_VALUE</code> are represented as "<code>Infinity</code>".</p>
<p>Because <code>MAX_VALUE</code> is a static property of {{jsxref("Global_Objects/Number", "Number")}}, you always use it as <code>Number.MAX_VALUE</code>, rather than as a property of a {{jsxref("Global_Objects/Number", "Number")}} object you created.</p>

<h3 id="Example:_Using_MAX_VALUE" name="Example:_Using_MAX_VALUE">Example: Using <code>MAX_VALUE</code></h3>
<p>The following code multiplies two numeric values. If the result is less than or equal to <code>MAX_VALUE</code>, the <code>func1</code> function is called; otherwise, the <code>func2</code> function is called.</p>
<pre class="brush: js">if (num1 * num2 &lt;= Number.MAX_VALUE) {
  func1();
} else {
  func2();
}
</pre>
