Math Class static double log10(double d)

• This method is available in java.lang package.
• This method is used to return the logarithm of the given (base 10) of the given argument in the method.
• This is a static method so it is accessible with the class name too.
• The return type of this method is double, it returns the logarithm (base 10) of the given argument.
• In this method, we pass only one parameter as the double type whose logarithm (base 10) to be found.
• This method does not throw any exception.

Syntax:

    public static double log10(double d){
    }

Parameter(s): It accepts a double value, whose logarithm (base 10) to be found.

Return value:

The return type of this method is double, it returns the logarithm (base 10) of the given argument.

Note:

• If we pass "NaN", it returns "NaN".
• If we pass an argument which is equal to 10*n (n should be an integer type), it returns the n.
• If we pass a positive infinity, it returns the same (positive infinity).
• If we pass zero (-0 or 0), it returns the negative infinity.

Java program to demonstrate example of log10(double d) method

// Java program to demonstrate the example of 
// log10(double d) method of Math Class

public class Log10Method {
    public static void main(String[] args) {
        // Here we are declaring few variables
        double d1 = 7.0 / 0.0;
        double d2 = -0.0;
        double d3 = 6054.2;

        // displaying values
        System.out.println("d1: " + d1);
        System.out.println("d2: " + d2);
        System.out.println("d3: " + d3);

        // Here , we will get (Infinity) because we are 
        // passing parameter whose value is (-infinity)
        System.out.println("Math.log10(d1): " + Math.log10(d1));

        // Here , we will get (-Infinity) because we are 
        // passing parameter whose value is (-0.0)
        System.out.println("Math.log10(d2): " + Math.log10(d2));

        // Here , we will get (log [10 raised to the power of 
        // the given argument]) and we are passing parameter 
        // whose value is (6054.2)
        System.out.println("Math.log10(d1): " + Math.log10(d3));
    }
}
