In Ada you don't need to play around with memory 
allocation/reallocation/deallocation as much in other lower level 
languages. If you know in advance the maximum number you are going to 
have then you could use a discriminated array, e.g.

    type Number_Of_Floats is range 0 .. 20;
    --  Never going to be more than 20.

    type Array_Of_Floats is array (Number_Of_Floats range <>) of Float;

    type Group_Of_Floats (Length : Number_Of_Floats := 0) is record
       F : Array_Of_Floats (1 .. Length);
    end record;

    My_Floats : Group_Of_Floats;
begin
    ...

If you really don't know the number of items you are going to have then 
use one of the many container libraries available - you wouldn't 
re-invent the wheel and re-code the STL if you were using C++ would you?

Here is a link to a page of such libraries:

Look under "Data Types".
