Explicit Cast Insertion Transformation: Making Type Conversions Visible

Part of our transformation series in emmtrix Studio

What is Explicit Cast Insertion?
This transformation adds explicit type casts where implicit conversions would normally occur. It improves clarity, avoids unintended behavior, and supports more precise static code analysis.

Why use it?

▪️ Makes type conversions transparent
▪️ Helps prevent compiler warnings
▪️ Improves maintainability
▪️ Supports analysis in strongly typed systems

Example
The image below shows a before/after comparison where implicit conversions (e.g. in function calls, conditionals, ternary expressions) are replaced by explicit casts. Program behavior remains unchanged, but type handling becomes fully visible.

Integration
Available via #pragma directives or the GUI in emmtrix Studio. Semantics are preserved.
