Decimal DataType Question

What would I have to set the Decimal DataType's precision value to to accept:

5.5
0
1.5
3.5

etc...etc...?How large will the largest number be? Is there always at most a single decimal?

decimal(9,1) would work if you never have more than a single decimal palce. This would take up 5 bytes of storage, and nothing smaller would save you any space, so I would certainly leave it at that even if the number of digits to the left of the decimal (whole numbers) never exceeds 1.|||I've been experimenting and I think (4, 1) is going to work for me.
I just needed 0, 0.5, 1, 1.5, all the way up to 6.

Thanks!|||That is good, but keep in mind that even (4,1) is going to use the same 5 bytes of storage that (9,1) will. If there is ever any change of it getting larger, the extra space will not cost you anything.

Glad you got it going!
