How to output octal values in ColdFusion

Question

I have a series of octal values I'd like to output in their ASCII character equivalents. CHR does not seem to recognize an octal character when it sees it. Is there any straightforward way of doing this with ColdFusion?

Answer 1

Use InputBaseN to convert from Octal to Decimal, then you can use Chr to output the character.

For example:

Chr(InputBaseN( 101 , 8 ))    => A

To go back the other way, you can reverse the process with Asc and FormatBaseN:

FormatBaseN( Asc('A') , 8 )   => 101
