Functions

[Piro24]

Ok, I have a question about functions, and don't say read the tutorial, because I did and I don't get it still, hence this is why I'm asking.

I made a program which converts binary into decimal, and I want to know how to properly put it into a function. The converter is simple:

code:

for i : 1 .. length (binary)     if binary (i) = "1" then         decimal += 2 ** (length (binary) - i)     end if end for

I just want to properly incorporate it into a function which I can call upon for the result of binary to decimal.

It would be something like this:

code:

function bin_to_dec (bin : string) : int     var decimal := 0     for i : 1 .. length (bin)         if bin (i) = "1" then             decimal += 2 ** (length (bin) - i)         end if     end for     result decimal end bin_to_dec
