Measurements in aspect ratio, trim tool.

[Miltrin 5]

Hello, everybody again.
I have a problem trying to crop a photo with the exact aspect ratio that Instagram requests for its publications.
Instagram asks for the following ratios, 1:1, 4:5 or 1.91:1
The first two I accept without problems, my problem is when I want to crop an image with the horizontal aspect ratio 1.91:1 I can not place decimals.
I tried to do a mathematical operation to make it into Pixels and I got the following measure 1080x565,45 px with the maximum width that Instagram asks for. But in Pixels I can't place decimals either, it's a bug or I can't really set this kind of measurements.

Thank you very much if you can help me.

The Instagram Help I looked at did not say to use an aspect ratio of 1.91:1. It suggested a ratio between 1.91:1 and 4:5.

A ratio of 1.91:1 can work only for images that are 191x100, 382x200, 573x300, etc. because images cannot contain a fraction of a pixel. They only contain complete pixels.

Ok I understand, thanks for your response.
However, do not you think it should be possible to put 1.91: 1 in the measurement fields in the aspect ratio option?

However in the AF preference options, if we can place how many decimals we want for Pixels. Attached image, if I think it's like that. If you do not apologize for my ignorance.

Perhaps it should be possible, but 191:100 works just as well, so it's not very important to me.

I'll use it that way, thanks again.
