For integers beyond 64 bit, or even beyond 32 bit on a 64 bit machine,
why can't the math be broken down into peices the way a human does 
it on

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

Re: [fpc-pascal] A jit tool for command line compilation of Pascal?

[Stuart Cox]

Yes, thanks.  Couldn't seem to track it down.

Several years ago I seem to remember using a FPC tool that allowed
me to write Pascal code and have its source file loaded, compiled

kept access to the environment that it was being executed
immediately under and so was like a Pascal .bat or .cmd.

Can anyone refresh my memory, please?
