Java exp() Method

Java Number Class

The exp() method is used to return e (the base of natural logarithms) raised to the power of the argument.

Syntax

This method has the following syntax formats:

double exp(double d)

Parameters

• d-- any primitive data type.

Return Value

Returns e raised to the power of the argument.

Example

public class Test{ 
    public static void main(String args[]){
        double x = 11.635;
        double y = 2.76;

        System.out.printf("e 的值为 %.4f%n", Math.E);
        System.out.printf("exp(%.3f) 为 %.3f%n", x, Math.exp(x));  
    }
}

Compile the above program, the output result is:

e 的值为 2.7183
exp(11.635) 为 112983.831
