MySQL Numeric Functions Examples
The following examples help you to understand these mathematical functions in MySQL
MySQL Trigonometric Functions Example 1
In this example, we are going to use the ABS to find the absolute positive value. Next, we used the ACOS, ASIN methods to find the Arc cosine, and Arc Sine values.

SELECT ACOS(1), ACOS(0), ACOS(0.5), ACOS(0.75);
SELECT ASIN(0), ASIN(0.25), ASIN(0.50), ASIN(1);
Trigonometric Functions Example 2
In this example, we are going to use the ATAN and ATAN2 to find the Arctangent value of single and double arguments. Next, we used the COS to find Cosine value.
SELECT ATAN(4), ATAN(24), ATAN(-32);
SELECT ATAN2(1, 5), ATAN2(-2, 3), ATAN(3.5, 0);
SELECT COS(0), COS(1), COS(2.5), COS(0.25);
MySQL Numeric Functions Example 3
In this example, we are going to use the CEIL, CEILING to find the closest value. Next, we applied the CONV method to convert the given value based on the given base.
SELECT CEIL(1.25), CEIL(1.95), CEIL(-2.3), CEIL(-2.90);
SELECT CEILING(7.98), CEILING(6.01), CEILING(-22.93);
SELECT CONV('A', 16, 2), CONV('G', 18, 8);
Numeric Functions Example 4
In this instance, we are going to use the MySQL COT, DEGREES, and EXP mathematical functions.
SELECT COT(5), COT(1), COT(15);
SELECT DEGREES(3.14), DEGREES(PI() / 2), DEGREES(2);
SELECT EXP(0), EXP(2), EXP(-2);
MySQL Mathematical Functions Example 5
In this MySQL Mathematical functions example, we are going to apply the EXP, FLOOR, and FORMAT.
SELECT EXP(0), EXP(2), EXP(-2);
SELECT FLOOR(2.89), FLOOR(2.05), FLOOR(-2.25), FLOOR(-2.97);
SELECT FORMAT(543212.1245, 2), FORMAT(1121343.87965, 4);
MySQL Mathematical Functions Example 6
In this example, we are going to practice the LN, LOG, LOG2 to find the Natural Logarithmic Value, and Log base 2 value.
SELECT LN(2), LN(5), LN(-5);
SELECT LOG(2), LOG(2, 250), LOG(10, 250);
SELECT LOG2(250), LOG2(24567), LOG2(-23234);
Numeric Functions Example 7
Here, we are going to use the LOG10 function to find the Logarithmic value of base 10. Next, the MOD to find the remainder, and PI method to get the PI value.
SELECT LOG10(250), LOG10(1000), LOG10(2500);
SELECT MOD(250, 7), MOD(59, 9), 600 MOD 16;
SELECT PI(), PI() MOD 2;
MySQL Mathematical Functions Example 8
In this MySQL Mathematical functions example, we use the POW and POWER to find the Power. Next, we applied the RADIANS to convert Degrees to radians.
SELECT POW(3, 2), POW(25, 5), POW(16, 2);
SELECT POWER(3, 2), POWER(25, 5), POWER(16, 2);
SELECT RADIANS(90), RADIANS(180), RADIANS(360);
MySQL Mathematical Functions Example 9
In this example, we are going to use the RAND to return random value, SIGN method to find the sign. Next, we used the ROUND method to round the decimals.
SELECT RAND(), RAND(5);
SELECT ROUND(-12.25), ROUND(-12.67), ROUND(14.268, 1);
