Example

<!--- This example shows the use of IsBinary. It assumes that another page in a
syndication program passed this page the value of the variable data_var,
which can hold character or binary data. This example checks whether
data_var is binary; if so, it converts the data to Base64 data. --->
<h3>IsBinary Example</h3>

<!--- Check whether syndicated data is in binary form. If so, convert to Base64
so it can be viewed as printable characters. --->
<cfif IsBinary(data_var)>
  <cfset Base64data = ToBase64(data_var)
</cfif>

The text under the section heading "Return Value" is nonsense. First, it says that the return value is "true" or "false", then it says that it returns "the value" base64 encoded.

Also, the entire page suffers from the same problems as all of the ColdFusion documentation: the information is often not specific or complete enough to actually use it.
