There are two general categories of types in SXEmacs Lisp: those having to do with Lisp programming, and those having to do with editing. The former exist in many Lisp implementations, in one form or another. The latter are unique to SXEmacs Lisp.
| • Integer Type: | Numbers without fractional parts. | |
| • Floating Point Type: | Numbers with fractional parts and with a large range. | |
| • Character Type: | The representation of letters, numbers and control characters. | |
| • Symbol Type: | A multi-use object that refers to a function, variable, or property list, and has a unique identity. | |
| • Sequence Type: | Both lists and arrays are classified as sequences. | |
| • Cons Cell Type: | Cons cells, and lists (which are made from cons cells). | |
| • Array Type: | Arrays include strings and vectors. | |
| • String Type: | An (efficient) array of characters. | |
| • Vector Type: | One-dimensional arrays. | |
| • Bit Vector Type: | An (efficient) array of bits. | |
| • Function Type: | A piece of executable code you can call from elsewhere. | |
| • Macro Type: | A method of expanding an expression into another expression, more fundamental but less pretty. | |
| • Primitive Function Type: | A function written in C, callable from Lisp. | |
| • Compiled-Function Type: | A function written in Lisp, then compiled. | |
| • Autoload Type: | A type used for automatically loading seldom-used functions. | |
| • Char Table Type: | A mapping from characters to Lisp objects. | |
| • Hash Table Type: | A fast mapping between Lisp objects. | |
| • Range Table Type: | A mapping from ranges of integers to Lisp objects. | |
| • Weak List Type: | A list with special garbage-collection properties. |
