Convert integer value to hexadecimal in Ada

Question

Is there any workaround to take advantage of the following and save it?

Put_Line(MyNum, Base => 16); 

which converts, for example, 255 to its correct value in hexadecimal FF, but only for display. Can I do something similar but save the result?

Answer 1

You can use the version Put these outputs on a line :

 procedure Put(To : out String; Item : in Num; Base : in Number_Base := Default_Base); 

Answer 2

Is it possible to do something similar, but save the result?

Yes, this is not the “easiest” way, but it is very general and flexible if you use Streams.

There is an example on wikibook, although it is a bit “verbose” for your intention: http://en.wikibooks.org/wiki/Ada_Programming/Libraries/Ada.Streams/Example

The simple "one line" is Ada.Integer_Text_IO.Put .

Ada95 RM describes integer_text_IO in Appendix A, 10.8.
