Determining Display Aspect Ratio *spawn

[Davros]

That would be the aspect ratio.

sure but you wouldnt know that until you actually calculate ii
eg: 3271x1693 only after trying every number from 1 to 3271 would you know its prime. like I said not a trivial problem

Luckily I found a great online calculator here : https://andrew.hedges.name/experiments/aspect_ratio/ (just enter numbers into w1 and h1)
so I'd never need to work it out for myself.
I tried viewing the source for the page to see how it was done but the formula seems to be in a file called <script type="text/javascript" src="/experiments/aspect_ratio/behaviors.js"></script> but I have no access to it.

It's a javascript file, of course you have access to it. It's simply text.

A slight mistake there - it says PAL aspect ratio is 5:4. By resolution it would be, but it is intended to be presented in 4:3 with non square pixels... Thus all this fuss about aspect ratio calculation goes down the drain for that case.

That would be the aspect ratio.

Also you can set one to '1' like cinema does 1.85 : 1 or 2.39 : 1

Resolution 859 x 461, aspect 859 : 461, or ~1.86 : 1

read somewhere that the SNES aspect ratio was 64:49. Beat that

well that was silly since no tv had that ratio
