A few days ago, I realized that using abs( can save space!

Code:
`:If X=1 or X=5`
use

Code:
`:If 2=abs(X-3`

Code:
`:If A>2 and A<10`
use

Code:
`:If 4>abs(A-6`

save space at the cost of speed. My initial reaction is that using abs( the way you describe would be a great slowdown
Another trick to save space: change
N/5
to
5-1N
All abs( does is make the argument positive, though

...and you have the subtraction in there, as well. And remember, this is all being done on a 9-byte floating-point number
better yet max(X={2,5,34,25

How does taht save any space? It's still the same number of tokens.
Not if it's a complex expression (complex as in complicated):
(B-CA)/5
as opposed to
5-1(B-CA

One byte saved.
But it still goes slower.
5-14589
is slower than
(4589)/5

And adding parenthesis goes slower. So the -1 trick is good to save space but not to improve speed.

Also, when doing
fpart(9-1dim(L1
fpart(9-1*9
returns 1
int(9-1*9 returns 0

even if the dim of L1 = 3, there will be an fpart.
Yes, it does indeed go slower. Therefore it's a size optimization, not a speed optimization.
I did some tests today, and the abs( routine is about 17% faster.

post the code you used

Code:
```:starttmr->S :For(X,1,10000 :A=1 or A=5 :End :Disp checktmr(S :starttmr->S :For(X,1,10000 :2=abs(A-3 :End :Disp checktmr(S```

17% faster than what?

Code:
``` :If X=1 or X=5```

use

Code:
``` :If 2=abs(X-3```

Code:
``` :If A>2 and A<10```

use

Code:
``` :If 4>abs(A-6```

Or

Code:
`:If max(X={1,5`

?
Ooh, forgot about the max( one. I'll test that out.

Edit: Yay! The abs( routine is about 28% faster than the max( one!
I discovered that one byte and precisely one millisecond can be saved from:
round(rand,0
randInt(0,1
Thanks Kerm! I'll use that in my Sudoku program! (84 bytes saved so far! )
Heh, good for you. I'm thinking of making a mini-contest of Scrabble AIs to see if someone can come up with a better method than my recursive solver.
