That should work. This works for me:
julia> function f(x)
y::Float64 = 4.5
y = x + 5 + y
return y
end
f (generic function with 1 method)
julia> f(5)
14.5
However, there are some subtleties, have a look at the manual
http://docs.julialang.org/en/latest/manual/types/
(The preferred style, I think, is not leave no space between a function
name and (...).)
