Java log10() with example

The java.lang.Math.log10() is one of the Java Math Library method which is used to return the base 10
logarithmic value of given double value as a parameter. There are various cases :

• If the argument is positive double value, Math.log10() method will return the logarithm of a given
  value.
• If the argument is NaN or less than zero, Math.log10() method will return NaN.
• If the argument is positive infinity, Math.log10() method will return the result as Positive Infinity.
• If the argument is positive or negative zero, Math.log10() method will return the result as Negative
  Infinity.

Syntax :

public static double log10(double a)

Parameter :

a : User input

Return :

This method returns the base 10 logarithm of a.

Example :To show working of java.lang.Math.log10() method.








// Java program to demonstrate working // of java.lang.Math.log10() method import java.lang.Math;    class Gfg {        // driver code     public static void main(String args[])     {            double a = 1000;         double b = 145.256;         double c = -6.04;         double d = 1.0 / 0;         double e = 0;            // A power of 10 as input         System.out.println(Math.log10(a));            // positive double value as argument,         // output double value         System.out.println(Math.log10(b));            // negative integer as argument,         // output NAN         System.out.println(Math.log10(c));            // positive infinity as argument,         // output Infinity         System.out.println(Math.log10(d));            // positive zero as argument,         // output -Infinity         System.out.println(Math.log10(e));     } }

Output:

3.0
2.1621340805671756
NaN
Infinity
-Infinity
