Third option is to use oct() and hex() based on pattern

~/perl -le 'print hex("0xdeadbeef")'
3735928559
~/perl -le 'print oct("0177")' #also handles 0b
127

my $match = /^\s*0([xb])?[0-9a-f]+?/;
my $num;
if( $match && $1 eq 'x' ){ $num = hex() }
elsif( $match && ( $1 eq 'b' or $1 eq undef) ){ $num = oct() }
else{ $num = $_+0 }
