in reply to 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;

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

    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";
