I agree that

0 1
1 0
is more comprehensible than
6 b./~ 0 1

I think the implementation is correct, though it lets you use numbers
larger than the specified base, and always returns an integer in base 10:
4b5 NB. 5 > 4 but no problem
5
4bz
35
This is the same behaviour as #. :
4 #. 5
5
4 #. 1 1
5
when using base specification using b, J lets yo

The 'b' notation is useful when importing numbers which were
originally supplied in non-base-10 format. (Hexadecimal, octal and
binary are relatively
Hi Yves,
I'm not sure how you're interpreting J's base number notation but it is
certainly correct in the examples you mention.
For instance, 5 in base 4 is indeed 11 because 5=+/1 1*4^1 0 or "1" in the
1s column plus 1 in the 4s column equals 5. In fact this is exactly the
same as substituting

Dear All,
