Re: convert to binary number

You can use the %b template in printf:

my $int = 123;
printf "%b\n", $int;

Update: Another option is to use pack + unpack.

my $int = 123;
say unpack "B*", pack "n", $int;

If you need that binary sequence stored in a string value, you could use `sprintf`like so: `my $int = 123; my $bin = sprintf "%b", $int; my $fix = sprintf "%08b", $int; print "Integer $int is binary $bin (eight-digit binary: $fix)\n";` [download]	[reply] [d/l] [select]
