What are the performance implications of that? It's basically adding an extra operation. Also, having been one to dive into intermediate assembly from time to time, there certainly are people who complain about the obtuseness of object code. Particularly since the generated object code is (out-of-order execution notwithstanding) how the CPU is going to actually execute the instructions.

Um, what? C has native floating-point types on every platform with an IEEE-754-compliant FPU, and probably on some that don't as well. Pointers are also not integers, though bad programmers frequently coerce them into such because most compilers will let them.

[spion]

Regarding "|0", there are absolutely no performance implications. An ASM.js optimising compiler will recognize these code patterns and interpret them completely differently (it will not execute a bit OR operation, and instead will only treat |0 as a type hint)
