<p><code>Infinity</code> is a property of the <em>global object</em>, i.e. it is a variable in global scope.</p>
<p>The initial value of <code>Infinity</code> is {{jsxref("Number.POSITIVE_INFINITY")}}. The value <code>Infinity</code> (positive infinity) is greater than any other number. This value behaves mathematically like infinity; for example, any positive number multiplied by <code>Infinity</code> is <code>Infinity</code>, and anything divided by <code>Infinity</code> is 0.</p>
<p>Per the ECMAScript 5 specification, <code>Infinity</code> is read only (implemented in JavaScript 1.8.5&nbsp; / Firefox 4).</p>
