DEGREES(), DIV() and EXP() Function in MariaDB

1. DEGREES() Function : In MariaDB, The DEGREES Function converts a radian value into degrees. In this function, a number will be passed as a parameter and it will return a degree of the radian value. Syntax :

DEGREES(number)

Parameter : Required. A value in Radians. number : Value in radians that is to be converted to degrees. Returns : Degree equivalent of the value input in radians. Example-1 : 

SELECT DEGREES(-3.5);

Output : 

-200.53522829578813

Example-2 : 

SELECT DEGREES(PI()*3);

Output : 

540

Example-3 : 

SELECT DEGREES(1);

Output : 

57.29577951308232

2. DIV() Function : In MariaDB, The DIV Function used for integer division where n is divided by m and integer value is returned. In this function, two numbers will be passed as a parameter and it will return the result as an integer value. It can also be used with BIGINT values. Syntax : 

n DIV m

Parameters : Required. Two integer values.

• n : Dividend (Value that will be divided).
• m : Divisor (Value which the dividend is being divided by).

Returns : An integer value as the result of the division. Example-1 : 

SELECT 11 DIV 4;

Output : 

3

Example-2 : 

SELECT 18 DIV 9;

Output : 

2

Example-3 : 

SELECT 18.4 DIV -2.5;

Output : 

-7

3. EXP() Function : In MariaDB, The EXP Function returns e raised to the power of number (or e^number). In this function, a number will be passed as a parameter and it will return e raised to the power of number. In this function e is the base of natural logarithms. Syntax : 

EXP(number)

Parameter : Required. A numeral value. number : Power to raise e to, so the formula would be e^number. Returns : e raised to the power of the input number. Example-1 : 

SELECT EXP(2);

Output : 

7.38905609893065

Example-2 : 

SELECT EXP(2.5);

Output : 

12.182493960703473

Example-3 : 

SELECT EXP(-2.5);

Output : 

0.0820849986238988
