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
