Hi, everyone,

I had a need for performing a bit-wise OR operation today and checked  
the manual for the proper notation. The Manual says:

"Opcodes that perform arithmetic and logic operations are -, +, &&,  
||, *, /, ^, and %."

The double vertical bar is apparently the symbol for logical OR, but  
when I use it I get an error. After much trial-and-error, I found the  
a single vertical bar gets accepted by Csound version 5.09 (float  
samples) Sep 22 2008, and appears to give me the expected result (1 |  
2 gives 3)

So how come the manual shows this as a double bar?

ALSO, what's going on under the hood? I thought numerical values were  
floating point (in the floating point version.) If so, can I still  
safely use bit-wise computations for numbers up to, say 256? or 65565?

thanks, and Happy New Year!

-Lou

In languages with C syntax, | is bitwise OR where

binary 01 OR 10 -> binary 11

and || is local OR where

binary 01 OR 10 -> logical TRUE, any non-zero value, usually1 or -1.

Hope this helps,
Mike

Thanks, Mike,

Your answer, together with the statement in the manual:

>> "Opcodes that perform arithmetic and logic operations are -, +, &&,
>> ||, *, /, ^, and %."
>>

...suggests that I can compute boolean expressions in csound, since,  
as you said, || is a logical OR, while | is a binary OR. But I was  
under the impression that csound used only one computational type:  
floating point.

Further, the manual doesn't mention the single-bar version as far as I  
can tell, only the double-bar version (as in the above quotation.)

Is the statement I quoted above just an error? (Same comments for &&  
and &, I suppose...)

I don't know, sorry.

Bitwise would still work with floating point numbers, since they are
after all made of bits. But I suspect that Csound uses | for logical
OR.

Hi,

Just checking it now, Csound does bitwise operations on integers. See:






instr 1
iresultOr = p4 | p5
iresultAnd = p4 & p5
prints "%i | %i  = %i\\n", p4, p5, iresultOr
prints "%i & %i  = %i\\n", p4, p5, iresultAnd
endin



i 1 0 0.1  1  2
i 1 +  .   1  3
i 1 +  .   2  4
i 1 +  .   3  10
e



Cheers,
Andrés

A bitwise OR can be used as a logical OR, but not vice versa. In other words,

binary 00100 | 00010 -> 00110 which is != 0 which is logically TRUE.

Yes, Andres,

I made the same test. And I have no problem doing bitwise computations  
on floating point numbers to achieve my intentions. On small numbers  
I'm reasonably sure that I won't have to worry about the exponent  
portion of two floating point numbers being different.

However, the manual for some reason lists || for logical OR, not |.  
And yet csound treats || as an error but handles | as you indicated.  
Since I don't speak C (but I do speak Java) I was wondering if I  
missed something. From what everyone is saying, it seems it's just an  
error in the manual that for some reason hasn't bothered anyone.

Hi Lou,

Can you post the line that gives the error, I'm curious.

Hi Lou -

as far as I see the manual is correct in listing || for logical OR,  
because something like
   if 1 > 0 || 2 < 0 then
   print i1+i2
   endif
is ok. In your example
	k1 = 1
	k2 = 2
	k3 = k1 || k2
	printk2 k3
	k4 = k1 & k2
	printk2 k4,3
you don't use a boolean expression in combination with ||, so it's not  
working.
So, at the end, the manual saying
>>>>>> "Opcodes that perform arithmetic and logic operations are -, +,  
>>>>>> &&,
>>>>>> ||, *, /, ^, and %."
>>
seems to be correct for me, as && and || are logic operations (and the  
others arithmetic).

Or am I missing something? At least I learned something about bitwise  
and / or from the discussion. Best -

	joachim

Joachim,

Thanks for this clarification. I see better the distinctions between  
logical, arithmetic and other operators now.

I suppose that what I was expecting, but csound doesn't provide, is a  
boolean data type. This would allow logical computations outside of IF  
statements and would allow for storing the result in a variable and  
then re-using the computation elsewhere.

But almost the same can be accomplished with bitwise operations.

best,
Lou
