Round float with Julia 1.1

New to Julia

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

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)

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.

To be fair though, this table about rounding functions links to the TimeType-related (ie dates) methods for round, which is probably a bit confusing. Should this be fixed?
