I prefer not to give any numbers (not even ballpark). It is extremely dependent on the benchmark, the JS engine, execution order (which function is optimized first, and/or inlined, ...). Things get more complex if you want to implement the double/integer distinction that exists in Dart. That would either require to box integers or doubles, or to come up with some kind of tagging.
