Impact of migration to Visual Studio 2019 on floating-point operations

Visual Studio is used to build and compile C and C++ components in IBM® Cognos® Analytics with Watson. As a result of upgrading Visual Studio to version 2019, you might notice some discrepancies between floating-point operation results in Cognos Analytics 11.2.1 and Cognos Analytics 11.2.0 and previous versions.

In general, floating-point operations in Visual Studio 2019 are more accurate.
