POW
POW is a mathematical function in SQL that returns the power of a number. It calculates the value of a number raised to the power of another number.
POW(X,Y);
- x: The base number that will be raised to the power of Y. This can be any numeric constant, variable, or expression.
- y: The exponent to which the base number X is raised. This can also be any numeric constant, variable, or expression.
Example
Output
Explanation
The available function POW(base, exponent) returns the value of the base argument raised to the power of the exponent argument. In this case, it’s calculating 5 to the power of 3, which equals 125.
POW( float_expression , y )
- float_expression: A floating point number which serves as the base for the power function.
- y: A floating point number representing the exponent to which the base number is raised.
Example
Output
Explanation
The POW function in SQL returns the value of a number raised to certain power. In the given example, the number 2 is raised to the power of 3, returning the result 8.
POW(n number, m number) RETURN number;
- n number: This is the base number. It signifies the number that will be raised to the power of another number.
- m number: This is the exponent number. It shows the degree to which the base number will be raised.
- return number: This is the output of the function. It signifies the result obtained after raising the base number to the power of the exponent number.
Example
Output
Explanation
In this example, the POW
function raises the number 3 to the power of 4. When executed, it returns the result 81.
POW(x, y)
- x: This is the base number. It is the value that is to be raised to a certain power. x can be any real number.
- y: This is the exponent. It’s the number that determines how many times the base will be multiplied by itself. y can also be any real number.
Example
Output
Explanation
The above SQL command calculates the power of a number. The function POW(2,3)
returns 2 to the power of 3, which equals 8.0 in SQLite.
