Transact SQL :: Select Closest Lower Value From A List With A Parameter

What I'm trying to select is the closest value from a list given by a parameter or select the matched value.

declare @compare as int
set @compare = 8
declare @table table
(
Number int
)
insert into @table
values(1),
(2),
(3),
(4),
(5),
(10)

If the parameter value match one of the values from the table list, select that matched one.If the value does not exist in the table list, select the closest lower value from the table list, in this case, it would be value 5.
