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}"
s = Integer.to_string(i)

Integer.to_string checks if i is an Integer.
s = to_string(i)

Doesn't check if i is an Integer
Str(i,s);

No dependecies on any library.
Should work in all Pascal dialects.
