# Java Math - exp() Method

The Java exp() method returns e raised to the power of specified number, i.e., ex. Please note that e is the base of the natural system of logarithms, and its value is approximately 2.718282. In special cases it returns the following:

• If the argument is NaN, the result is NaN.
• If the argument is positive infinity, then the result is positive infinity.
• If the argument is negative infinity, then the result is positive zero.

### Syntax

```public static double exp(double x)
```

### Parameters

 `x` Specify the exponent of e.

### Return Value

Returns e raised to the power of specified number.

NA.

### Example:

In the example below, exp() method is used to calculate e raised to the power of specified number.

```public class MyClass {
public static void main(String[] args) {
System.out.println(Math.exp(2));
System.out.println(Math.exp(-2));
System.out.println(Math.exp(1.5));
System.out.println(Math.exp(-1.5));
}
}
```

The output of the above code will be:

```7.38905609893065
0.1353352832366127
4.4816890703380645
0.22313016014842982
