Correct. And also in pil64 and pil21.
All other arithmetic operations except add/sub cannot

"Pico operates on lists. Its fundamental data structure tends toward linear
algorithms."
This is what you've been told? Plain wrong!
(cons(cons(A B) C) already is a minimal (directed) graph.
What does that (200 lines of C) Lisp implementation tell you?

Certainly, Fusion Tree, as well as the successor, Exponetial Tree and
especially Van Emde Boas Tree have certain "overhead". But it pays off

I took my algorithms class from one of the inventors of fusion trees. Itâs
more of a stunt than anything else. He invented it just to prove the point.
The constant factor of each operation dwarfs the comparison it avoids. But
the big-O is relatively small. They are still impractical.

For heavy number crunching, picolisp might not be appropriate. In modern
systems you would probably want something that used the vector
instructions. But if itâs a few divisions here and there, youâd be
surprised how little the efficiency in clock cycles matters anymore.

Hello all,
I would like to ask that structure sharing is used in pil32 bigNums or not ?
In doSub(), doAbs() it uses structure sharing, but otherwise in big.c
it copies the argument then modifies it.
Thanks,
