[Numpy-discussion] We've recevied a NumFOCUS SDG!
Hello NumPy community, I am thrilled to announce that I have been awarded a NumFocus Small Development Grant for my work on NumPy-Financial. This grant will enable me to enhance compatibility with NumPy 2.0, attract new contributors, improve testing and documentation, and perform the UFunc rework. I'm looking forward to contributing to the scientific Python community! As part of this grant, I am looking for any NumPy-Financial users input, especially in regard to setting up some benchmarks of real world scenarios. If you are currently using NumPy-Financial please get in touch. I hope everyone is going well Kai ___ NumPy-Discussion mailing list -- numpy-discussion@python.org To unsubscribe send an email to numpy-discussion-le...@python.org https://mail.python.org/mailman3/lists/numpy-discussion.python.org/ Member address: arch...@mail-archive.com
[Numpy-discussion] NumPy-Financial: RFC: Dropping decimal.Decimal support
Hi all, I'm currently working NumPy-Financial (npf) and would like to ask for comments on dropping decimal.Decimal support in npf. I'm proposing to drop Decimal support for npf. There are a few reasons for this: 1. No one appears to use decimal types. Since it's release in 2019, not a single issue has been raised that uses decimal support. Furthermore, I have taken a quick survey of dependent projects, none of which seems to use decimals. 2. It's not actually supported that thoroughly. Npf claims that: “Functions support the :class:`decimal.Decimal` type unless otherwise stated.”. This isn't technically true. Many functions that claim to support decimal classes don't. I think it would be better to have a consistent interface that would either entierly support decimal or not support it at all. 3. I'm currently working on mimicking broadcasting behaviour for functions. This involves lots of for loops. To speed these up I will use either numba or Cython. Neither of these support decimal classes natively. If you have any comments on whether this seems to be the right option, I would be very interested in hearing it.

[Numpy-discussion] Moving busday functionality to numpy-financial
TLDR: There has been some discussion regarding moving busday and related functions to numpy--financial. The sentiment for this has generally been positive, this thread is to assess the amount of work required to move these functions. Dear NumPy Maintainers, There has been some discussion about moving np.busday* to numpy-financial first on GitHub [1] and more recently on Slack. The sentiment has largely been positive, however one concern is that the amount of work required is not justified as few people currently use these functions and the move could be messy. I have recently been contributing to NumPy and am currently the sole maintainer of numpy-financial, so it feels like I am the right person to do this. In my opinion, these functions conceptually fit the scope of numpy-financial. However, I have some hesitations about this work. Namely, I am struggling to estimate the scope of this work and I have only some experience with C, and the NumPy C API. I am having trouble estimating the amount of work this would require, but suspect that it will not be easy. The functions use some of the internal C-API (I think, how do I find out the differences between the internal/external API?) and depends on `np.datetime`. Further, the busday* functions are implemented in C. I only have some experience with C and the C aspects of NumPy—I am happy to learn, but this seems like a pretty steep learning curve. Finally, numpy-financial is currently a pure Python module and does not build C, again I will either need help with this or to learn how to do this. To finish, I have a few questions / requests for advice: * Is this change supported by the NumPy community? * Does anyone have advice on how to estimate the amount of work required? * If I start working on this, would anyone be willing to help me learn the C components?
