The IEEE 754 specification defines many floating point types, including: binary16, binary32, binary64 and binary128. Most developers are familiar with binary32 (equivalent to float in C#) and binary64 (equivalent to double in C#). They provide a standard format to represent a wide range of values with a precision acceptable for many ...

Last month, we announced .NET support for Jupyter notebooks, and showed how to use them to work with .NET for Apache Spark and ML.NET.

It's about two years ago that I announced .NET Standard 2.0. Since then we've been working hard to increase the set of .NET Standard-based libraries for .NET. This includes many of the BCL components, such as the Windows Compatibility Pack, but also other popular libraries, such as the JSON.NET, the Azure SDK, or the AWS SDK. In this blog post...

For .NET Core 3.0, we're shipping a brand new namespace called System.Text.Json with support for a reader/writer, a document object model (DOM), and a serializer. In this blog post, I'm telling you why we built it, how it works, and how you can try it. We also have a video: Getting the new JSON library If you're targeting .NET...

Ron Petrusha (MSFT)
Typically, calendar eras represent long time periods. In the Gregorian calendar, for example, the current era spans (as of this year) 2,019 years. In the Japanese calendar, however, a new era begins with the reign of a new emperor. On April 30, 2019, Emperor Akihito is expected to abdicate, which will bring to an end the Heisei era. On the ...

Mads Torgersen
Building C# 8.0 The next major version of C# is C# 8.0. It's been in the works for quite some time, even as we built and shipped the minor releases C# 7.1, 7.2 and 7.3, and I'm quite excited about the new capabilities it will bring. The current plan is that C# 8.0 will ship at the same time as .NET Core 3.0. However, the features will ...
