Question

I have a variable of type Number, and i like to obtain the sign (if is ‘-‘ i like to have -1 and if ‘+’ i like to have 1). So, i made this:

var sign = Math.abs(n) / n; 

But, there is any other way? Better than this?

Answer 1

You’ll be in trouble if n == 0… how about this:

var sign = n < 0 ? -1 : 1;
