C++ Float to Int Conversion (How To Guide) | by ryan - Medium
These functions return a float, which is then implicitly converted to int. Be cautious: for very large floats, this implicit conversion can ...
How to actually convert float to int? - Arduino Forum
The implicit conversion will cause an overflow when you assign it to a long . The behavior is undefined in C++ for signed integer overflow ...
The overflow when converting from float to integer is undefined ...

triggers undefined behavior. Yes, that's what I suspected after I tried Andrew's example. ... change float to double and everything will be fine.
Why does making int* to float* conversions undefined behavior help ...
This performs an implicit conversion from type float to type int , resulting in n having the value 3 (the conversion truncates). The code is ...
floating point to integer casts can cause undefined behaviour #10184
A flag has been implemented in the compiler, -Zsaturating-float-casts, which will cause all float to integer casts have saturating behavior.
