The large majority of math functions is specific to applications using trigonometry, calculus, and geometry. This is very important and it is very difficult to have all of them together at place.

Math Functions

Absolute value **ABS**

Arc cosine **ACOS**

Arc sine **ASIN**

Arc tangent of n **ATAN**

Arc tangent of n and m **ATN2**

Smallest integer >= value **CEILING**

Cosine **COS**

Hyperbolic cosine **COT**

Exponential value **EXP**

Round down to nearest integer **FLOOR**

Natural logarithm **LOG**

Logarithm, base **10 LOG10**

Modulus (remainder) **USE MODULO (%) OPERATOR**

Power **POWER**

Random number **RAND**

Round **ROUND**

Sign of number **SIGN**

Sine **SIN**

Square root** SQRT**

Tangent **TAN**

Convert number if **NULL ISNULL**

Standard deviation **STDEV**

Variance **VAR**

Out of all the above functions, RAND is the only one which is Nondeterministic Functions. Deterministic functions always return the same result any time they are called with a specific set of input values and given the same state of the database. Nondeterministic functions may return different results each time they are called with a specific set of input values even if the database state that they access remains the same. You cannot influence the determinism of any built-in function. Each built-in function is deterministic or nondeterministic based on how the function is implemented by SQL Server.

is there a way to do a division and modulo in the same statement? I’d like the result of the division to go into one variable and the remainder into another.

How to get highest value from 5 local variables in a stored procedure.

Eg:

Declare @var1 as int, @var2 as int, @var3 as int, @var4 as int, @var5 as int

Set @var1=55

Set @var2=70

Set @var3=90

Set @var4=90

Set @var5=25

I need value distinct 90 as it is highest among all variables. I mentioned distinct because it repeats in @var3 and @var4 both.

Thanks

create table temp(col1 integer)

select * from temp

DECLARE @temp TABLE(col1 INTEGER)

DECLARE @r int=55

DECLARE @s int=70

DECLARE @t int=90

DECLARE @q int=70

DECLARE @x int=90

INSERT INTO temp(col1) values(@r)

INSERT INTO temp(col1) values(@s)

INSERT INTO temp(col1) values(@t)

INSERT INTO temp(col1) values(@q)

INSERT INTO temp(col1) values(@x)

SELECT MAX(col1) FROM temp

How to get a quotient of two numbers ? what is the function used to get it ?

SQUARE() Float expression

Square of the given numeric expression. Equivalent of POWER function when raised to 2nd power. Example:

SELECT SQUARE(3)

9

SELECT SQUARE(9);

SELECT POWER(9,2);

It’s So Nice.
