Trouble with Ada.Streams.Stream_Element

Trouble with Ada.Streams.Stream_Element

[Frank Gerlach]

It is defined as follows:
type Stream_Element is mod 2 ** Standard'Storage_Unit;
I would like to convert it to an INTEGER.
How do I do this ?

Thanks for helping a newbie !

What about:  Integer(A_Stream_Element) ?

Stream_Element is already a perfectly good numeric type; why do you
want to convert it to another numeric type? 

If it's because you want to write it to a text file, instantiating
Ada.Text_IO.Modular_IO is better.

But if you insist, this is just a numeric type conversion: 

A : Stream_Element := 2;
B : Integer := Integer (A);

Have you had a chance to look at some stream examples?
For example, you could use

 Integer'read(your_input_stream, your_integer_variable);

Usually a program just reads from a stream, it doesn't
have to look at individual bits.

Or are you implementing a new stream class?
