thanks Janardhan, in that case I would recommend to go with R syntax
because (1) it's actually one of our selling points that users don't have
to learn a new language, (2) it simplifies the porting of R scripts to DML
(and vice versa), and (3) I would think it's rather uncommon to have long
chains
Could we please stick to R syntax (i.e., "xor(a, b)") here, unless there is
a good reason to deviate? Thanks.
Regards,
Matthias

Hi all, [XOR symbol]
Now, I gave a sample try for the XOR operator, with caret ` ^ ` symbol.
But, this have been reserved for exponentiation. So, another alternative
would be
1. ` (+) `
2. ` >< `
3. ` >-< `
Thanks,
Janardhan

>From a scalar operation perspective, you could of course emulate XOR via
AND, OR, and negation. However, you might want to write anyway a java-based
UDF to efficiently implement this recursive operator.

Hi,
The following is an equation (2.4) from the algorithm for the generation of
sobol sequences. The authors of the paper have utilized the bitwise
operations of C++ to calculate this efficiently.
*Now, the question is:* Can we do this at script level (in dml) or we
should do it in the `java`
