That is, Math.exp(4.0) = e4.0
.
The syntax of the exp()
method is:
Math.exp(double a)
Here, exp()
is a static method. Hence, we are accessing the method using the class name, Math
.
exp() Parameters
The exp()
method takes a single parameter.
- a - number to raise e to
exp() Return Values
- returns ea for the argument a
Note: Here, e is the Euler's number whose value is 2.71828
Example: Java Math.exp()
class Main {
public static void main(String[] args) {
// Math.exp() method
double a = 4.0d;
System.out.println(Math.exp(a)); // 54.598150033144236
// without using Math.exp()
// value of Euler Number
double euler = 2.71828d;
System.out.println(Math.pow(euler, a)); // 54.5980031309658
}
}
In the above example, we have used the Math.pow() method to compute the value of e4.0. Here, we can see that
Math.exp(4.0) = e4.0
