Thank René!

Re: [julia-users] When to use Symbol instead of ASCIIString on function arguments?

There is no difference. identity is defined as "identity(x) = x", and this gets inlined by the compiler. You can also check, for example, the output of "@code_native f(1)" and compare it with g. Am 30.08.2015 um 16:06 schrieb Diego Javier Zea : > Thanks! > > One more question, what is the di

Thanks! One more question, what is the difference between this two definitions: julia> f(x) = x f (generic function with 1 method) julia> g(x) = identity(x) g (generic function with 1 method) julia> f(10) 10 julia> g(10) 10

Thanks! I didn't know about enum types!

Since functions are first class objects, my answer would be "neither, just use a function": methoda = x -> one(typeof(x)) + x methodb = identity On Sat, Aug 29, 2015 at 11:17 AM Diego Javier Zea wrote: > Hi! > > I'm confused with this... > > When do I need to use Symbol instead of ASCIIString on

Hi! I'm confused with this... When do I need to use Symbol instead of ASCIIString on function arguments? Which of the following is the best and Julian definition? julia> myfunstr{T}(x::T; method::ASCIIString="one") = method=="one" ? one(T )+x : x myfunstr (generic function with 1 method) ju
