C++ float-to-int conversion can be undefined behavior
Summary
The article explains that converting a float to an int in C++ can cause undefined behavior when the value doesn't fit the destination type. It covers how implicit and explicit casts can silently produce UB across platforms, references safe narrowing approaches like gsl::narrow, and suggests using bounds checks or sanitizers (UBSan) to detect issues, with a pointer to safer, saturating casting approaches.
