<p>When normalizing <strong>xsd:double</strong> values, implementers MUST
ensure that the normalized value is a string. In order to generate the
-string from a <strong>double</code> value, output equivalent to the
+string from a <strong>double</strong> value, output equivalent to the
<code>printf("%1.6e", value)</code> function in C MUST be used where
<strong>"%1.6e"</strong> is the string formatter and <strong>value</strong>
is the value to be converted.</p>
+<p>To convert the a double value in JavaScript, implementers can use the
+following snippet of code:</p>
+
+<pre class="example" data-transform="updateExample">
+<!--
+// the double value to convert to a JSON-LD normalized string
+var value = 2.33333333333;
+// Convert the value, producing the equivalent output to printf("%1.6e", value);
+var s = (value).toExponential(6);
+s = s.substring(0, s.indexOf('e') + 2) +
+ (s.indexOf('e') == s.length - 3 ? '0' : '') +
+ s.substr(s.indexOf('e') + 2);
+-->
+</pre>
+
<p class="note">When data needs to be normalized, JSON-LD authors should
not use values that are going to undergo automatic conversion. This is due
to the lossy nature of <strong>xsd:double</strong> values.</p>
