tgcnzn / javascript aspect ratio calculation (with GCD)

Created January 19, 2018 02:11 — forked from phobeo/javascript aspect ratio calculation (with GCD)

javascript aspect ratio calculation algorithm (take the GCD and divide both elements of resolution)

	/* euclidean GCD (feel free to use any other) */
	function gcd(a,b) {if(b>a) {temp = a; a = b; b = temp} while(b!=0) {m=a%b; a=b; b=m;} return a;}

	/* ratio is to get the gcd and divide each component by the gcd, then return a string with the typical colon-separated value */
	function ratio(x,y) {c=gcd(x,y); return ""+(x/c)+":"+(y/c)}

	/* eg:
	> ratio(320,240)
	"4:3"
	> ratio(360,240)
