RE: bitand functions and NUMBER(20)

I'm curious how you're establishing the value that Oracle is returning.

This could possibly just be a problem with the column format not being wide
enough for a fully expressed displayed answer.

Subject: bitand functions and NUMBER(20)

Hi all,
I have got a column defined as NUMBER(20) and want to use bit functions on
it. 
It seems that oracle bitand function is restricted in length. To give an 
example:
select bitand(10846370260800065548,9368617832122679304) from TABLE;
returns 9.2234E+18, although the second figure is a subset of bits in first 
figure. So result should be 9368617832122679304.
To make sure my figures are right, I did
select 10846370260800065548 & 9368617832122679304;
in Mysql and it gave 9368617832122679304.
The problem does arise with figures of a certain length.
What to do best (apart from changing the column type, which I would like to 
avoid)?
I hope the question isn't too trivia...
Stefan
