Then don't use the same variable ;) ``` julia> a = 10;
julia> _a = a; julia> f(x) = _a * x; julia> f(2) 20 julia> a = 20; julia> f(2) 20 ``` This has nothing to do with pass-by-sharing, but rather with scoping - the manual talks quite a lot about this (but don't hesitate to suggest improvements if something is unclear to you!) http://docs.julialang.org/en/release-0.4/manual/variables-and-scoping/ // T On Friday, October 9, 2015 at 4:26:38 PM UTC+2, Thuener Silva wrote: > > I understand the pass-by-sharing concept, but if I want to use only the > value of a variable? > Simple example to illustrate what I'm trying to say: > > julia> a = 10 > 10 > > julia> f(x) = a*x > f (generic function with 1 method) > > julia> f(2) > 20 > > julia> a = 20 > 20 > > julia> f(2) > 40 > > I don't wan to to change the function when I change the value of a. > > Grats, > Thuener Silva >
