# Java Math - pow() Method

The java.lang.Math.pow() method returns the first argument raised to the power of the second argument. In special cases it returns the following:

• If the second argument is positive or negative zero, then the result is 1.0.
• If the second argument is NaN, then the result is NaN.
• If the first argument is NaN and the second argument is nonzero, then the result is NaN.
• If the second argument is 1.0, then the result is the same as the base.

### Syntax

```public static double pow(double a, double b)
```

### Parameters

 `a` Specify the base. `b` Specify the exponent.

### Return Value

Returns the first argument raised to the power of the second argument.

NA.

### Example:

In the example below, pow() method is used to calculate the first argument raised to the power of the second argument.

```import java.lang.*;

public class MyClass {
public static void main(String[] args) {
System.out.println(Math.pow(2, 3));
System.out.println(Math.pow(2.3, 4));
}
}
```

The output of the above code will be:

```8.0
27.98409999999999
```
