math sample for UPB ================================ the following application is for learning purposes. That's it, babe. features: - **addition** adds - **multiplication** multiplies - **division** Guess what, just a division - **fibonacci** well

var call_counter=require("./call_counter");

function multiply(x,y){
	call_counter();
	return x*y;
}
function divide(x,y){
	call_counter();
	return x/y;
}
function fibo(count){
	call_counter();
	return private_fibo(count);
}
function private_fibo(count,counter,first,second){
	if (count==0){
		return 0;
	}
	if (counter==undefined){
		counter=1;
		first=1;
		second=2;
	}
	result = first+second;
	if(counter==count){
		return result;
	}
	private_fibo(count,++counter,second,result);
	return result;
}

module.exports={
	multiplication:multiply,
	division:divide,
	fibonacci:fibo
}
