Hello, I am trying to round a number to the 3rd decimal with Julia 1.1 but I have issues:

```julia
julia> beta
0.005208333333333333
julia> round(beta, 3)
ERROR: MethodError: no method matching round(::Float64, ::Int64)
Closest candidates are:

  round(::Float64, ::RoundingMode{:Up}) at float.jl:368
  round(::Float64, ::RoundingMode{:Down}) at float.jl:366
  ...
Stacktrace:

julia> round(beta, Up)

ERROR: MethodError: objects of type RoundingMode{:Nearest} are not callable
Stacktrace:
 [1] top-level scope at none:0
julia> round(beta, RoundNearest)
0.0
julia> ceil(beta)
1.0

```

what is the current sintax to round a float to the n digit?

You’re probably looking to old documentation? `round(beta, 3)` is an old syntax, before Julia v0.7

Relevant documentation is [here](https://docs.julialang.org/en/v1/base/math/#Base.round-Tuple%7BType,Any%7D).

To be fair though, [this table about rounding functions](https://docs.julialang.org/en/v1/manual/mathematical-operations/#Rounding-functions-1) links to the `TimeType`-related (ie dates) methods for `round`, which is probably a bit confusing. Should this be fixed?
