x ÷ k is faster than floor(Int, x/k). Is there an ceiling division function that rounds up instead of down, equivalent to but faster than ceil(Int, x/k)? julia> f(x) = floor(Int, x/4) f (generic function with 1 method) julia> g(x) = x÷4 g (generic function with 1 method) julia> @benchmark f(x) se…

yes, there is :slight_smile: https://docs.julialang.org/en/v1/base/math/#Base.cld
