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:

Syntax	xxxxxxxxxx 1 package java.lang; 2 3 public final class Math { 4 5 public static double log10(double x) { ... } 6 7 } Note: Classes in the `java.lang` package are imported automatically, so it is not necessary to do it manually - we use just `Math.log10()` call.
Parameters	`x` - double value in the range `0` to `+Infinity` (primitive value).
Result	`number` value calculated as log_10(x) mathematical function (primitive value). If `x` is negative it returns `NaN`. If `x` is equal to `0` it returns `-Infinity`. If `x` is equal to `+Infinity` it returns `-Infinity`.
Description	`log10` is a static method that takes one parameter and returns an approximation of the log_10(x) mathematical function (logarithm with base `10`). `log10` is called a common logarithm.
