// # Write a method that takes in a number and returns true if it is a
// # power of 2. Otherwise, return false.
// #
// # You may want to use the `%` modulo operation. `5 % 2` returns the
// # remainder when dividing 5 by 2; therefore, `5 % 2 == 1`. In the case
// # of `6 % 2`, since 2 evenly divides 6 with no remainder, `6 % 2 == 0`.
// #

function isPowerOf2(num){
	var base = Math.log2(num);
	if(Number.isInteger(base))
	return true;
	else
	return false;
