A little late to the party, but I thought I would mention that this was fixed in 2015. Here is the GitHub issue. Example usage:

public void Issue261_Decimals()

    var parameters = new DynamicParameters();
    parameters.Add("c", dbType: DbType.Decimal, direction: ParameterDirection.Output, precision: 10, scale: 5);
    connection.Execute("create proc #Issue261 @c decimal(10,5) OUTPUT as begin set @c=11.884 end");
    connection.Execute("#Issue261", parameters, commandType: CommandType.StoredProcedure);
    var c = parameters.Get("c");
    c.IsEqualTo(11.884M);
}
