Online Java pow() function

public class Main { public static void main(String[] args) { double x = 28; double y = 4; // return the maximum of two numbers System.out.println("Maximum number of x and y is: " +Math.max(x, y)); // return the square root of y System.out.println("Square root of y is: " + Math.sqrt(y)); //returns 28 power of 4 i.e. 28*28*28*28 System.out.println("Power of x and y is: " + Math.pow(x, y)); // return the logarithm of given value System.out.println("Logarithm of x is: " + Math.log(x)); System.out.println("Logarithm of y is: " + Math.log(y)); // return the logarithm of given value when base is 10 System.out.println("log10 of x is: " + Math.log10(x)); System.out.println("log10 of y is: " + Math.log10(y)); // return the log of x + 1 System.out.println("log1p of x is: " +Math.log1p(x)); // return a power of 2 System.out.println("exp of a is: " +Math.exp(x)); // return (a power of 2)-1 System.out.println("expm1 of a is: " +Math.expm1(x)); } }
