  (string-to-number string &optional base)

  Parse string as a decimal number and return the number.
  This parses both integers and floating point numbers.
  It ignores leading spaces and tabs.

  If base, interpret string as a number in that base.  If base isn't
  present, base 10 is used.  base must be between 2 and 16 (inclusive).
  If the base used is not 10, floating point is not recognized.

so

  (char-to-string (string-to-number "0a" 16)) => "\n"
