WebLISP - Data Types. In LISP, variables are not typed, but data objects are. LISP data types can be categorized as. Scalar types − for example, number types, characters, symbols etc. Data structures − for example, lists, vectors, bit-vectors, and strings. Any variable can take any LISP object as its value, unless you have declared it explicitly. WebCommon Lisp automatically coerces numeric values among these types as appropriate. The Common Lisp character type is not limited to ASCII characters. Most modern implementations allow Unicode characters. The symbol type is common to Lisp languages, but largely unknown outside them. A symbol is a unique, named data object with several …
