What has changed:
- new types si:complex-float, si:complex-single-float,
si:complex-double-float and si:complex-long-float
- new builtin classes long-float (for completness) and
si:complex-float
- new internal function si:complex-float and si:complex-float-p for
constructing complex floats (both arguments must be of the same
float type) and a type predicate
- printer for new types (right now it conses, see below)
- a new feature :complex-float
- a new type is recognized as a type disjoint of complex and real
- cleanup: +built-in-type-list+: remove some redundancy
For instance instread of saying
(real (or integer single-float double-float ratio))
We say
(real (or integer float ratio))
etc.
Flaws which will be fixed in upcoming commits:
- complex-float hierarchy is independent of the complex hierarchy
- ecl_make_complex_float could be replaced by _ecl_make_complex_*float
- write_complex_float allocates new objects for printing
- write_complex_float does print unreadable object
- math dispatchers doesn't recognize the object
Testing things out:
> (si:complex-float 0.0d0 0.0d0)
; #<CF(0.0d0 0.0d0)>
> (si:complex-float 0.0d0 0.0s0) ; signals type error
> (+ (si:complex-float 0.0d0 0.0d0) 1) ; signals type error
lisp runtime: make si_complex-float a subtype of a number.

ECL stands for Embeddable Common-Lisp. The ECL project aims to produce an implementation of the Common-Lisp language which complies to the ANSI X3J13 definition of the language.
The term embeddable refers to the fact that ECL includes a Lisp to C compiler, which produces libraries (static or dynamic) that can be called from C programs. Furthermore, ECL can produce standalone executables from Lisp code and can itself be linked to your programs as a shared library. It also features an interpreter for situations when a C compiler isn't available.
ECL supports the operating systems Linux, FreeBSD, NetBSD, DragonFly BSD, OpenBSD, Solaris (at least v. 9), Microsoft Windows (MSVC, MinGW and Cygwin) and OSX, running on top of the Intel, Sparc, Alpha, ARM and PowerPC processors. Porting to other architectures should be rather easy.
