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() methodimport 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
