Idiom #55 Convert integer to string

Create the string representation s (in radix 10) of the integer value i.

Turning the integer 123 into the string "123" 
$s = "$i";

Interpolation of variables allows to put them inside a string
my $s = "" . $i;

Perl automatically converts numbers to strings, and strings to numbers, whenever required. The concatenation with the empty string is superfluous, it only indicates programmer intent.
S : String := Integer'Image (I);
