courbet added a comment. OK, here's an analysis of 100 instances of a check that would warn on all fully implicit (no C/static/reinterpret/...) casts from float/double to integral: link <https://docs.google.com/document/d/1X1ostfsvwEDD3I4LLSKgDIF131lAUElRUg2ONyr_Xjg/edit?usp=sharing> I don't expect the analysis to be perfect, but that gives us a better idea of what to expect.
- A bit more than 1/3 of instances are OK and should be using a cast. - A bit less than 1/4 of instances is brittle code and should use int types. - The two false positive cases are easy to handle. - I was surprised about the "truth value of float" one. I think we should provide a fix to turn `!f` this into `f != 0.0f`.
