ALP Rust is faster than C++

cppreference says [1]:

    A prvalue of floating-point type can be converted to a prvalue of any integer type. The
    fractional part is truncated, that is, the fractional part is discarded.

    - If the truncated value cannot fit into the destination type, the behavior is undefined (even
      when the destination type is unsigned, modulo arithmetic does not apply).

Ugh. Like, surely the C++ stdlib could provide a "give me the best int approximation" function without triggering nasal demons. Sometimes I feel like C++ is not just difficult to use but actively trying to harm me.
