The syntax of the log10()
method is:
Math.log10(double x)
Here, log10()
is a static method. Hence, we are calling the method directly using the class name Math
.
log10() Parameters
- x - the value whose logarithm is to be computed
log10() Return Values
- returns the base 10 logarithm of x
- returns NaN if x is NaN or less than zero
- returns positive infinity if x is positive infinity
- returns negative infinity if x is zero
Note: The value of log10(10n) = n
, where n is an integer.
Example: Java Math.log10()
class Main {
public static void main(String[] args) {
// compute log10() for double value
System.out.println(Math.log10(9.0)); // 0.9542425094393249
// compute log10() for zero
System.out.println(Math.log10(0.0)); // -Infinity
// compute log10() for NaN
double nanValue = Math.sqrt(-5.0);
System.out.println(Math.log10(nanValue)); // NaN
// compute log10() for infinity
double infinity = Double.POSITIVE_INFINITY;
System.out.println(Math.log10(infinity)); // Infinity
// compute log10() for negative numbers
System.out.println(Math.log(-9.0)); // NaN
//compute log10() for 103
System.out.println(Math.log10(Math.pow(10, 3))); // 3.0
}
}
In the above example, notice the expression,
Math.log10(Math.pow(10, 3))
Here, Math.pow(10, 3)
returns 103. To learn more, visit Java Math.pow().
