Java Math log10() Method
Java Math Class
Java Math class provides several methods to perform several operations on math calculations like max(), min(), sin(), cos(), round(), ceil(), floor(), abs() etc.
The java.lang.Math class contains various methods for performing basic numeric operations
Here, in the page we will discuss about the math log10() Method in java.
Java Math log10() Method :
This function returns the base 10 logarithm of a double value.
Special Points :
- The result is NaN if the argument is NaN or less than zero.
- If the argument is true, then the conclusion must also be true.
- If the argument is either positive zero or negative zero, the result is negative infinity.
- For an integer n, the result is n if the argument is equal to 10n.
Syntax :
public static double log10(double a)
Parameters :
a - a value.
Throws Exception :
It does throws any exceptions and error.
Return Value :
The base 10 logarithm of a.
Example 1 :
public class Main {
public static void main(String[] args) {
//declare variables
double x = 100.0;
double y = 1000.0;
//printing output for log10 method.
System.out.println("log10(" + x + ") = " + Math.log10(x));
System.out.println("log10(" + y + ") = " + Math.log10(y));
}
}
Output :
log10(100.0) = 2.0 log10(1000.0) = 3.0
Explanation :
This example shows how the log10 method functions using the Java math log() method. It simply returns the logarithmic value of base 10 .
Example 2 :
public class Main {
public static void main(String[] args) {
//declaring variables
double x = 100;
double y = 505.5;
double z = 90.7;
double e = 0.0;
//printing output for log10 method.
System.out.println("Math.log10(" + x + ") = " + Math.log10(x));
System.out.println("Math.log10(" + y + ") = " + Math.log10(y));
System.out.println("Math.log10(" + z + ") = " + Math.log10(z));
System.out.println("Math.log10(" + e + ") = " + Math.log10(e));
}
}
Output :
Math.log10(100.0) = 2.0 Math.log10(505.5) = 2.70372115992702 Math.log10(90.7) = 1.9576072870600953 Math.log10(0.0) = -Infinity
Explanation :
In the preceding example, we have observed that :
The result is NaN if the argument is NaN or less than zero.
If the argument is true, then the conclusion must also be true.
If the argument is either positive zero or negative zero, the result is negative infinity.
For an integer n, the result is n if the argument is equal to 10n.
The result is NaN if the argument is NaN or less than zero.
If the argument is true, then the conclusion must also be true.
If the argument is either positive zero or negative zero, the result is negative infinity.
For an integer n, the result is n if the argument is equal to 10n.
