Perl in a Nutshell, 2nd Edition

Name

oct

Synopsis

oct ostring
                  

Interprets ostring as an octal string and returns the equivalent decimal value. (If ostringhappens to start with 0x, it is interpreted as a hex string instead.) The following will handle decimal, octal, and hex in the standard notation:

$val = oct $val if $val =~ /^0/;

If ostring is omitted, the function interprets $_. To perform the inverse function on octal numbers, use:

$oct_string = sprintf "%lo", $number;
