The Math.pow() function is an in-built function in Javascript that returns a number equal to the base number raised to its exponent. It takes two parameters - the base and the exponent.
- base: It is the base number that is to raised.
- exponent: It is the value used to raise the base.
Return Value
THe Math.pow() function in JavaScript returns a number that is equal to the base raised to its exponent. However, if the base is negative and the exponent if fractional, it returns NaN.
Exceptions
The Math.pow() in JavaScript returns NaN if the base is negative and the exponent is fractional. This is because wehn a negative number is raised to a fractional number, the resulting value can be an imaginary number.
base가 음수이고 exponent가 정수가 아닌 경우 NaN을 반환한다.
base가 NaN인 경우 또한 NaN을 반환한다. exponent도 마찬가지이다.
We store the output of the function in the vairable result. We are taking 2 as the base and 10 as the exponent. We are printing the output in Line 4. The output is 1024.
제곱근을 의미하여 Math.sqrt() function과 동일하다.
정의
- 지수 연산을 수행하는 메서드.
Syntax
- base: 지수 연산의 밑이 되는 숫자.
- exponent: 지수승을 나타내는 숫자.
Example
'Math.pow(2, 3)' => 2³으로 표현되어 8을 반출한다
conclusion
거듭제곱을 하겠다는 거다.
