Re: library class bit_string

[Gerrit Leder]

Hello,

please add to_boolean to library class bit_string!

I have formerly used BIT N to write an application. And it was possible to convert an entry (item) in BIT N to a boolean value.

Now I want to port this application to new library class bit_string and need the same feature here.


Thank you
Gerrit Leder

Why not, but, a time being, I have no idea of the purpose
of such a routine. Could you propose a short description,
what kind of assertions ans why not, the implementation!

Have a good day,

Function item already exists. Extract from short bit_string below:

   item (idx: INTEGER_32): BOOLEAN
      -- True if `idx'-th bit is 1, False otherwise.
      require
         valid_index(idx)
