Math.log(double a) has the following syntax.
public static double log(double a)
In the following code shows how to use Math.log(double a) method.
/* w w w.j a va 2 s . co m*/ public class Main { public static void main(String[] args) { double x = 123456.7; double y = -123.45; // get the natural logarithm for x System.out.println("Math.log(" + x + ")=" + Math.log(x)); // get the natural logarithm for y System.out.println("Math.log(" + y + ")=" + Math.log(y)); } }
The code above generates the following result.
