International System of Quantities (ISQ): Part 6 - Challenges
This article might be the last one from our series. This time, we will discuss the challenges and issues with modeling of the ISQ in software.
2024¶
mp-units 2.4.0 released!
A new product version can be obtained from GitHub and Conan.
This release was unexpected. We planned a significant new feature to happen next, but while preparing for it, and also while writing API Reference documentation, we made so many vital fixes and improvements that we decided that they deserve a dedicated release first.
This post describes the most significant improvements while a much longer list of the changes introduced by the new version can be found in our Release Notes.
International System of Quantities (ISQ): Part 5 - Benefits
In the previous articles, we introduced the International System of Quantities, described how we can model and implement it in a programming language, and presented the issues of software that does not use such abstraction to implement a units library.
Some of the issues raised in Part 2 of our series were addressed in Part 3 already. This article will present how our ISQ model elegantly addresses the remaining problems.
International System of Quantities (ISQ): Part 4 - Implementing ISQ
Up until now, we have introduced the International System of Quantities and described how we can model its main aspects. This article will present how to implement those models in a programming language, and we will point out some of the first issues that stand in our way.
International System of Quantities (ISQ): Part 3 - Modeling ISQ
The physical units libraries on the market typically only focus on modeling one or more systems of units. However, as we have learned, this is not the only system kind to model. Another, and maybe even more important, is a system of quantities. The most important example here is the International System of Quantities (ISQ) defined by ISO/IEC 80000.
This article continues our series about the International System of Quantities. This time, we will learn about the main ideas behind the ISQ and describe how it can be modelled in a programming language.
International System of Quantities (ISQ): Part 2 - Problems when ISQ is not used
This article is the next one in our series about the ISQ. After introducing the basic terms and systems, this article will talk about the issues we face when we base the quantities and units library on just units or dimensions.
International System of Quantities (ISQ): Part 1 - Introduction
This post starts a series of articles about the International System of Quantities (ISQ). In this series, we will describe:
- What is ISQ?
- Which engineering problems does ISQ help to solve and how?
- How to model and implement it in the programming language?
- What is missing in the ISQ, and why is that a problem?
mp-units 2.3.0 released!
A new product version can be obtained from GitHub and Conan.
This release fine-tunes many key features of the library. This post describes the most interesting improvements, while a much longer list of the changes introduced by the new version can be found in our Release Notes.
Report from the St. Louis 2024 ISO C++ Committee meeting
We made significant progress in the standardization of this library during the ISO C++ Committee meeting in St. Louis.
mp-units 2.2.0 released!
A new product version can be obtained from GitHub and Conan.
Among other features, this release provides long-awaited support for C++20 modules, redesigns and enhances text output formatting, and greatly simplifies quantity point usage. This post describes those and a few other smaller interesting improvements, while a much longer list of the most significant changes introduced by the new version can be found in our Release Notes.
