Saving 2 or 3 bytes of storage per row does not seem like a lot when compared with the 250+ GB hard drives that you can now purchase for with a relatively low price. Hard disk storage is a minor concern. If you store 1 million rows of data in a table, which is common, the bytes per row saved would add up to 2 MB to 3 MB of savings. Although that does not sound like a lot, consider that you would also save that much space in memory if a user were to execute a query that returned all the rows in the table, and it would also save thousands of processor cycles at the same time. The issue becomes even larger when you join two tables together. Joining two integer columns together consumes 8 bytes of memory as well as the corresponding calculation on the processor. If both tables held 1 million rows and needed to be read completely, it would consume about 8 MB of memory space. If you could have stored the data in a smallint or tinyint column instead, the memory savings for this query would be 4 MB 6 MB. You would also be transmitting 4 MB 6 MB of data across the network that would not be necessary. That is only for a single query. Consider what would happen if thousands of queries were being processed against the database and you can quickly see how 1 or 2 bytes of savings based on the data type you use can quickly make the difference between an environment with good performance and one with poor performance.

The approximate numeric data types can store decimal values. Data stored in a float or real data type is exact only to the precision specified in the data type definition. Any digits to the right are not guaranteed to be stored exactly. For example, if you store 1.00015454 in a data type defined as float(8), it is guaranteed to return only 1.000154 accurately. SQL Server rounds off any digits further to the right when it stores the number. Therefore, calculations involving these data types compound rounding errors. Transferring databases containing tables with these data types between Intel and AMD processors also introduces errors. Data Type float(p) Storage 4 or 8 bytes Value Range -2.23E308 to 2.23E308 -3.4E38 to 3.4E38 Purpose Stores large floating point numbers that exceed the capacity of a deci mal data type Still valid, but replaced by float to meet the SQL-92 standard

The float data types accept a parameter in the definition that determines the number of digits to store precisely. For example, a float(8) stores precisely 7 digits, and any thing exceeding that is subject to rounding errors. Because of the imprecision associated with these data types, they are rarely used. You should use float only in cases in which an exact numeric data type is not large enough to store the values.

Designing the Physical Database
The smallmoney data types are rarely defined in databases, even though they are the most accurate choices for many applications that deal with products and orders. It is much more common for these databases to incorrectly use a money data type and waste 4 bytes of storage for each row that is stored. Although money and smallmoney data types are designed to store currency values, they are rarely used in financial applications. Instead a decimal data type is used because many of these applications need to perform accurate calculations to 6, 8, and even 12 decimal places.
