Answer 1

From number to string:

(write-to-string 5)
"5"

you may transform a string to any numerical notation:

(write-to-string 341 :base 10)
"341"

From string to number:

(parse-integer "5")
5

with some trash

(parse-integer " 5 something not a number" :junk-allowed t)
5

Or use this:

(read-from-string "23 absd")
23
