Random Number Generator

Random Number Generator

[Hustler]

Does anyone know where the number generator is located, ie the package? Is
it in ada.elementary_functions packages or do I need to find a package that
contains a random number generator?

Thanks for the help

For pseudo-random floating-point random numbers, it's in the package
Ada.Numerics.Float_Random.  For pseudo-random integers and enumeration type
it's in the package Ada.Numerics.Discrete_Random.

Here's how you can answer a straightforward question like this
instantaneously for yourself.

Get an electronic copy of the Ada 95 RM (you can find this at
www.adapower.com for example).

Then search for the string "random" or else look up Random
in the index. Either approach will lead you to the appropriate
package immediately.

Has any one got a simple random number

If you have an Ada 95 compiler, the answer is simply to use the package
Ada.Numerics.Discrete_Random, which comes with the language.  This program
keeps displaying random integers from 1 to 10:

with Ada.Text_IO, Ada.Numerics.Discrete_Random;
use  Ada.Text_IO;
procedure Test is
  subtype S is Integer range 1 .. 10;
  package My_Random is new
       Ada.Numerics.Discrete_Random(S);
  use My_Random;
  G : Generator;
begin
  Reset(G);
  loop
    Put(Integer'Image(Random(G)));
  end loop;
end Test;

If you have an Ada 83 compiler, the answer is much more complicated, but the
compiler *may* have come with a package to do what you want.
