I can't tell what problem you're talking about. Ada.Text_IO's numeric-I/O pkgs, 
sometimes combined with String-handling functions and basic 1-D array operations 
seem to provide everything one could want.

Pkg PragmARC.Images has been around for a long time and provides generic Image 
functions for numeric types with width, zero-fill, and base options.
