Integers are whole numbers. Traditionally, SQL Server supported 1-, 2-, and 4-byte integers. SQL Server 2000 introduces an 8-byte integer. The bit data type is used to store 1 or 0, to represent logical true and false values. The following table lists integer data types, their storage size, and range of values.

The great thing about the int data types is that they can store huge numbers in a small space. For this reason, they are often used for key values. If the data type of the primary key is int, the table can store up to four billion records.
We are starting to see computers with billions of records both OLTP and data warehousing systems are getting bigger and bigger, and there are also some implementations of distributed databases that can use integers higher than two billion. In those cases you could use bigint for primary keys.
Integer constants do not need delimiters:
update Inventory_2 Set StatusId = 3, Operational = 0 Where InventoryId = 3432
Approximate Numbers
Decimal numbers are often stored in real and float data types, also known as single and double precision. Their advantage is that they do not occupy much space but they can hold large ranges of numbers. The only trouble is that they are not exact. They store a binary representation of the number that is often approximately, but not exactly, equal to the original decimal number. Precision is the number of significant digits in the number, and scale is the number of digits to the right of the decimal point. For example, the number 123456.789 has a precision of 9 and a scale of 3. The precision of real numbers is up to 7 digits, and the precision of float numbers is up to 15 digits. For this reason, they are ideal for science and engineering (where, for example, you may not care about a couple of meters when you are measuring the distance between the Earth and the Moon), but they are not adequate for the financial industry (where a company budget has to be exact to the last cent).
SQL Server 2000 Stored Procedure & XML Programming
To record the number 234,000,000,000 in mathematics, you can use 234 10 , and in Transact-SQL, you can use 234E9. This is known as scientific notation. The number after E is called the exponent, and the number before E is called the mantissa. This notation can be used to store small constants, too. In mathematics, 9 0.000000000234 can be written as 0.234 10 , and in Transact-SQL, it can be written as 0.234E-9. SQL Server uses the IEEE 754 standard to store these numbers. When a float or real variable or column is assigned a number, SQL Server first converts the decimal number to its binary representation. This conversion is the reason these values are approximately, but not exactly, equal to the decimal version. This is why they are referred to as approximate numbers. Therefore, you should not rely on the equivalence of two such numbers. You should limit their use in Where clauses to < and > operators and avoid the use of the = operator.
Exact Numbers
The decimal or numeric data type does not use approximations when storing numbers. Unfortunately, it requires much more space than the real and float data types. When a decimal column or a variable is defined, you have to specify its scale and precision. SQL Server can store decimal numbers with a maximum precision of 38. Scale can be less than or equal to the precision. In the next example, Weight and Height columns have precision 5 and scale 2 the columns can have up to two digits after the decimal point and up to three digits before.
Create table Patient (PatientId int, FullName varchar(30), Weight decimal(5,2), Height decimal(5,2), ADP smallint, BDZ tinyint) go
decimal constants do not need delimiters either:
insert into Patient (PatientId, FullName, Weight, Height, ADP, BDZ) values (834021, 'Tom Jones', 89.5, 188.5, 450, 11)
