Java - Math.log10() method example

The Math.log10() method returns the logarithm with base 10 of a number. 

public class MathExample {
    
    public static void main(String[] args) {
        // Logarithm with base 10:
        //                              x            y
        System.out.println( Math.log10( 1    ) ); // 0.0
        System.out.println( Math.log10( 3    ) ); // 0.47712125471966244
        System.out.println( Math.log10( 10   ) ); // 1.0
        System.out.println( Math.log10( 100  ) ); // 2.0
        System.out.println( Math.log10( 1000 ) ); // 3.0

        System.out.println( Math.log10( -1        ) ); //  NaN
        System.out.println( Math.log10(  0        ) ); // -Infinity
        System.out.println( Math.log10( Double.POSITIVE_INFINITY ) ); // +Infinity
    }
}

The Math.log10() method is presented on the following chart:
