Perl in a Nutshell

Name

oct

Synopsis

oct ostring

Description

Interprets ostring as an octal string and returns the equivalent decimal value. (If ostring happens to start off 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;
