Attempts to convert a value of any type, including a binary value, into a string.
ToString(any_value)
The value that is to be converted into a string.
If ToString cannot convert the value into a string, it throws an exception. All simple values can be converted into a string, even binary values that do not contain byte zero can be converted.
<!--- This example shows the use of ToBase64, ToBinary and ToString --->

<!----------------------------------------------------------------------
Initialize data.
----------------------------------------------------------------------->
<CFSET charData ="">
<!----------------------------------------------------------------------
Create a string of all ASCII characters (32-255) and concatenate them
together.
----------------------------------------------------------------------->
<CFLOOP index="data" from="32" to="255">
<CFSET ch=chr(data)>
<CFSET charData=charData & ch>
</CFLOOP>
<P>
The following string is the concatenation of all characters (32 to 255)
from the ASCII table.<BR>
<CFOUTPUT>#charData#</CFOUTPUT>
</P>
<!----------------------------------------------------------------------
Create a Base 64 representation of this string.
----------------------------------------------------------------------->
<CFSET data64=toBase64(#charData#)>
<P>
The following string is the Base 64 representation of the original
string.<BR>
<CFOUTPUT>#data64#</CFOUTPUT>
</P>
<!----------------------------------------------------------------------
Create a binary representation of Base 64 data.
----------------------------------------------------------------------->
<CFSET dataBinary=toBinary(data64)>
<!----------------------------------------------------------------------
Create the string repesentation of the binary data.
----------------------------------------------------------------------->
<CFSET dataString=toString(dataBinary)>
<P>
The following is the string representation of the binary data.<BR>
<CFOUTPUT>#dataString#</CFOUTPUT>
</P>
