string

string x → string

x — a string, a symbol, or a character.

string — a string.

Returns a string described by x; specifically:

• If x is a string, it is returned.

• If x is a symbol, its name is returned.

• If x is a character, then a string containing that one character is returned.

• string might perform additional, implementation-defined conversions.

(string "already a string") → "already a string" 
(string 'elm) → "ELM" 
(string #\c) → "c"

In the case where a conversion is defined neither by this specification nor by the implementation, an error of type type-error is signaled.

coerce, string (type).

coerce can be used to convert a sequence of characters to a string.

prin1-to-string, princ-to-string, write-to-string, or format (with a first argument of nil) can be used to get a string representation of a number or any other object.
