3.2.101 oct



This function interprets EXPR as an octal string and returns the equivalent decimal value. (If EXPR 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 EXPR is omitted, the function interprets $_ . To perform the inverse function on octal numbers, use:

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