I think that for floats, BLAS is used, while for integers it is native Julia code. The latter could probably be made faster, but it is not a common use case so it is waiting for someone to do it.

(also, please [quote code](https://discourse.julialang.org/t/psa-how-to-quote-code-with-backticks/7530))
