bad, bad field misuse. need to turn into to SQL.

I need to get length and width out of our item master via SQL..
database field defined: Packed 11,4 (IXXXX)


old, <charles barkley>TERRIBLE</cb> desire usage of field:
width: positions 1 -5, 3 decimal positions
length: positions 6-11, 3 decimal positions

good ole RPGII code to do this:

C IXXXX MULT 10000 IXXXX0 11 0
C MOVEL IXXXX0 IWIDE 5 3
C MOVE IXXXX0 ILENG 6 3


or, we also did...
D ds
D IXXX4 11 4
D Width 5 3 overlay(IXXX4:1)
D length 6 3 overlay(IXXX4:6)


C IXXX4 = IXXXX;


when I try the following:

select substr((IXXXX * 10000),1,5) as width, substr((IXXXX * 10000),6,6) as length, IPROD
from ......

I get my length and width as whole numbers, but when I try to push the math any further (by multiplying by .001), I get zeros in my fields...


I know my penitence will be great for this...
