Java Math log()

The Math.log() method in Java is used to find the natural logarithm of a number. It returns the value of the natural logarithm (base e) of the given argument.

Syntax:

public static double log(double num)

Parameters:

The log() method takes a single parameter of type double, which represents the number whose natural logarithm is to be found.

Return Value:

The log() method returns the natural logarithm of the given number, rounded to the nearest double value.

Example:

public class Example {
    public static void main(String[] args) {
        double x = 5.0;
        double result = Math.log(x);
        System.out.println("The natural logarithm of " + x + " is " + result);
    }
}

Output:

The natural logarithm of 5.0 is 1.6094379124341003

Note:

• If the argument of the log() method is 0.0, then the method returns -Infinity.
• If the argument of the log() method is negative, then the method returns NaN (Not a Number).

In conclusion, the Math.log() method is a useful tool to find the natural logarithm of a number in Java. It can be used in various mathematical calculations where the natural logarithm is required.
