[julia-users] Re: how to pass function as argument?

[cnbiz850]

Tried the following way and it worked. Wonder if anyone would comment on 
its properness?

------------------------
function f1(i::Int)
    x = 10. * i
    println(x)
    nothing
end
function f2(i::Int)
    x = 5. * i
    println(x)
    nothing
end

function func(ff)
    ff(4)
end

ff(i::Int) = f2(i::Int)

func(ff)

Say I want to pass the following function f1 to a function called f2 
as an argument.  What is exactly the type of function f1?  How do I 
define f2's arguments?

function f1(i::Int, x::Float)
    x = 10. * i
    nothing
end

function f2(f1::???)
end
