For integers beyond 64 bit, or even beyond 32 bit on a 64 bit machine,

paper, and then theoretically any number can be added and subtracted,
even if it is beyond 32/64 bit?

Example:

type TSuperLargeInt = string;

var
   i, j: TSuperLargeInt;
   output: TSuperLargeInt;
begin
   i := '10009';
   j := '10001';
   output := AddLargeInts(i,j);
   writeln(output);
end.


http://svn.code.sf.net/p/flyingsheep/code/trunk/wtf/ncalc.pp does 
exactly that

(all dependenies are also found at
http://svn.code.sf.net/p/flyingsheep/code/trunk/wtf).

It's not lightning fast, but there is room for optimization I guess.

I knew someone had already invented this!
Any idea if it does square roots, and, decimal point numbers too..

Or, what math can it "not" do.. things like sin/tan/cos, or strange 
maths..


Probably a complex question requiring a complex answer

I have found this:

https://stackoverflow.com/questions/25011141/turn-off-on-monitor-cant-turn-on

It's in c++, but it looks that since w.8, you must simulate a mouse move.

on without user input?  

I've tried 

progname := FindWindow('displaycontrol', nil);
PostMessage(progname, WM_KEYDOWN, VK_F5, 0);

And while the key sent to the program,  it does not wake the display up.   I 
see other examples of simulating keyboard input, but I haven't been able to get 
them to work in a freepascal console application.
