Description

For VerCors, I am working on implementing verification of programs that use floating point numbers (for my master thesis).
The way that I plan on implementing the support for floating point numbers is by using the real numbers, which are a part of Z3.

A similar tool to Viper, called Why3 (used by other verification tools such as FramaC) has support for real numbers, and Why3 is also based on Z3.

Would it be possible to give access to the real numbers through Viper?

Research direction

The issue does not name files, tests, or entry points. Start by clarifying how real numbers should be exposed through Viper and how the proposed Z3-based support should interact with existing numeric semantics. Done requires an agreed scope and implemented, verified support for real-number programs.
