The expl3 bundle: Low-level LaTeX3 programming conventions
The files of the expl3 bundle provide a low-level API for TeX programmers with special syntax conventions, completely separating it from document level syntax. Hence, the commands provided are not intended for use at the document level nor for use in describing design layouts in document class files.
This API provides the foundation on which the LaTeX3 kernel and other advanced extensions are built. Special care has been taken so that they can be used within a LaTeX2e context as regular packages.
The TeX and eTeX primitives are all given a new name according to these conventions. However, in the main direct use of the primitives is not required or encouraged: the expl3 modules define an independent low-level LaTeX3 programming language.
At present, the expl3 modules are designed to be loaded on top of LaTeX2e:
usepackage{expl3}
In time, a LaTeX3 format will be produced based on this code. This allows the code to be used in LaTeX2e packages now while a stand-alone LaTeX3 is developed.
This release (SVN 2020)
This update improves on the earlier l3fp implementation. This is now a floating point module, allowing for calculations across a wide range of input values. Current function coverage is:
- Arithmetic
- Sine, cosine and tangent
- Comparisons
- Conversion of fp data to other types
Other functions will be added over time, with priority given to those required by other parts of LaTeX3. Requests for specific functions to be added should be sent to the LaTeX-L list for discussion.
At the same time, a small number of issues with other parts of expl3 have been addressed. This includes some internal fixes and other refinements.

thanks for the upload; i've installed the new version and updated the catalogue repository.
the modest change to the catalogue entry won't hit the web until some time tonight.
