Examples of the MySQL Math Function
The math function operates in arithmetic, trigonometric and other mathematical operations. This function shows the functional values of the given data. The math function provides logarithm, square, squarer root, power, etc. This function determines sin, tan, cos, cot, and other trigonometric functions.
Examples of the basic function and its output
MySQL math function returns the pi value, square value, square root value, power of the required value. You can use a single math function or many math functions in a single query.
Example
MySQL math function returns the constant value of the "PI" function. You need to select the pi function. This function does need to include any value in the function.
mysql> select PI();OUTPUT
The pi function output returns the "3.14" value. This value uses in arithmetic and trigonometric operations.
Example
The given an example uses five functions to operate numerical value. This query works with square root, square and 5th power of the required value. Here, you operate the absolute value and a round number of the value.
mysql> select SQRT(4), power(4, 2), pow(4, 5), ABS(-4.213), round(3.99);OUTPUT
The above math functions return five functions output. This output needs to use a specific value. The first two column shows square root and square of the "4" value. The third column returns the 5th power of the "4" value. The fourth column function removes positive and negative signs and returns an only value.
Examples of the logarithmic function and its output
Execute logarithmic math function with its value. The log uses base 10, base 2, and natural base with the value. You can see the difference between logarithmic values. This function contains a "10" value in the required log.
mysql> select LOG(10), LOG10(10), LOG2(10), ln(10);OUTPUT
The above image shows you different log functions with the same value. The first and last columns show the natural log value. The second column shows base 10 log values. The third column shows the base2 log value.
Examples of the trigonometric function and its output
The trigonometric math function returns the side of the angle and arc of the value. Mysql math function provides SIN, COS, TAN, COT functions. Each function shows several values of the same angle.
Example
The example uses multiple operators or functions in a single query. This function contains a "30" value in the required log.
Mysql> select sin(30), cos(30), cot(30), tan(30);OUTPUT
The output table returns the value of the trigonometric function. You can get the sin, cos, cot, and tan output with 30 angles in the table. Each column displays a different arc value of the same angle.
Example
Execute the ATAN function with value. You can use two functions to get the arctangent of the data. This function contains 2 and 3 data.
Mysql> select ATAN2(2 , 3), ATAN(3, 2);
OR
Mysql> select ATAN(2 , 3), ATAN(3, 2);OUTPUT
This output image shows two arctangents with swapping numbers. The same number swaps in the same ATAN operator. This operator returns different output values in the table.
Examples of the arithmetical operations and their output
The math function supports addition, subtraction, division, and multiplication operations. You do not need a special function. The mod() function provides a reminder of the division. You can use select keywords, values and operators to get output.
Example
MySQL functions use an operator and two values to operate mathematical operations. The query uses addition (+), subtraction (-), division (/), and multiplication (*) operators. Here, the example uses 5 and 3 as the first value and second value, respectively.
Mysql> select 5 + 3,
5 - 3,
5 * 3,
5 / 3;OUTPUT
You can see the output values of the mathematical operations. The columns show 8, 2, 15, and 1.6667 values in the table.
Example
Execute mathematical operations using basic operators in the MySQL interface. The multiple operations combine and use in a single query.
Mysql> select 8 + 3 / 2 * 4 - 1;OUTPUT
The output returns values of the arithmetic operations. You can operation multiple operators simultaneously and get the 13.0000 value.
Example of the mathematical operations and their output
You can combine several arithmetical and trigonometric functions for mathematical operation. This example uses the pi value with sin(45) and the division operator. Execute the following math function with value.
Mysql> select pi() * sin(45) / 10;OUTPUT
The above image returns the output of the given math function. The sin(45) multiplies with the pi value and is divided by 10. The MySql returns the "0.2673" value in the output table.
