When it comes to working with numbers in programming, the power function is a handy tool. In most programming languages, the power function is denoted as **pow()**.

It allows you to raise a number to a specified exponent. But have you ever wondered, what data type does **pow()** return?

## The Return Data Type

The return data type of **pow()** depends on the programming language you are using. Let’s explore some popular programming languages and the data types returned by their respective power functions.

### JavaScript

In JavaScript, the **Math.pow()** function is used to calculate the power of a number. It returns a value of type __ number__. Here’s an example:

```
const result = Math.pow(2, 3);
console.log(typeof result); // Output: number
```

### Python

In Python, the built-in **pow()** function returns different data types based on its arguments:

- If both arguments are integers or floats, it returns a value of type
.*int* - If both arguments are complex numbers, it returns a value of type
.*complex* - If one argument is an integer and the other is a float or vice versa, it returns a value of type
.*float*

Here are some examples:

```
result_1 = pow(2, 3)
print(type(result_1)) # Output: int
result_2 = pow(2.5, 3)
print(type(result_2)) # Output: float
result_3 = pow(2+3j, 3)
print(type(result_3)) # Output: complex
```

### C++

In C++, the power function is provided by the **pow()** function from the **cmath** library. It returns a value of type __ double__. Here’s an example:

```
#include <iostream>
#include <cmath>
int main() {
double result = pow(2, 3);
std::cout << typeid(result).name() << std::endl; // Output: double
return 0;
}
```

## Conclusion

The return data type of the power function varies across different programming languages. In JavaScript, it returns a number, while in Python, it can return int, float, or complex depending on the arguments. In C++, the pow() function returns a double.

Knowing the return data type is important when you are performing operations or assigning values based on the result of a power function call. Make sure to check the documentation or language specifications to understand what data type to expect.

Now that you are aware of the return data types of various power functions, you can confidently use them in your programs without any surprises!
