you'll probably want to read a bit about fixed point notation. just like in grade school, keep track of the decimal point and you'll be in good shape

first, figure out how many bits you need to get a result that's good enough for your application. here's a table that will help:

1/10    width   2^width C/10   FLOOR(D) E/C
0.1	8	256	25.6	25.0	0.0976562500
0.1	9	512	51.2	51.0	0.0996093750
0.1	10	1024	102.4	102.0	0.0996093750
0.1	11	2048	204.8	204.0	0.0996093750
0.1	12	4096	409.6	409.0	0.0998535156
0.1	13	8192	819.2	819.0	0.0999755859
0.1	14	16384	1638.4	1638.0	0.0999755859
0.1	15	32768	3276.8	3276.0	0.0999755859
0.1	16	65536	6553.6	6553.0	0.0999908447

figure out how many integer bits you need. if you don't mind wasting a couple bits, and are using 2's compliment, you might leave the MSb as sign/integer and have the following bits be fraction bits. then in your product, note the location of the decimal point

this seems like somewhat of a common problem. this is basically a base10 barrel shifter, right?
