The java.lang.StrictMath.log10() is an inbuilt method in Java which accepts a double value as parameter and returns the base 10 logarithm of that value. Thus calculating the base 10 logarithmic value for a given parameter.
Syntax:
public static double log10(double val)
Parameters: The function accepts a double value, val as parameter whose base 10 logarithm is calculated.
Return Values: This function returns the base 10 logarithm of val based on the following conditions:
- The function returns NaN if argument passed is NaN or less than zero
- The function returns positive infinity if argument passed is positive infinity
- The function returns negative infinity if the argument passed is zero.
- The function returns a if the argument passed is
Examples:
Input : 2018.0 Output : 7.609862200913554 Input : 1000000.0 Output : 6.0
Below programs illustrate the working of java.lang.StrictMath.log10() :
Program 1: In this program , finite non-zero arguments are passed as parameter.
// Java Program to illustrate // StrictMath.log10() function import java.io.*;import java.lang.*; class GFG { public static void main(String[] args) { double val1 = 2018.00567 , val2 = 100000.0; // Argument passed is infinite System.out.println("Base 10 Logarithm of " + val1 + " is " + StrictMath.log10(val1)); // Passing zero as argument System.out.println("Base 10 Logarithm of "+ val2 +" is "+ StrictMath.log10(val2)); }} |
Output:
Base 10 Logarithm of 2018.00567 is 3.3049223821418496 Base 10 Logarithm of 100000.0 is 5.0
Program 2: In this program, infinity and zero are passed as parameter.
// Java Program to illustrate// StrictMath.log10() function import java.io.*;import java.lang.*; class GFG { public static void main(String[] args) { double val = 2018/(0.0); System.out.println("Base 10 Logarithm of " + val + " is " + StrictMath.log10(val)); System.out.println("Base 10 Logarithm of 0 is " + StrictMath.log10(0)); }} |
Output:
Base 10 Logarithm of Infinity is Infinity Base 10 Logarithm of 0 is -Infinity
