Can someone tell me what's wrong with function, please?

function rand(start, end) {
	return Math.floor((Math.random()*end-start)+start+1);
}

Math.floor((Math.random()*end-start)+start+1

It's wrong on that line.

function randomInRange(start, end) {
return Math.round(start + Math.random() * (end - start));
}
