Build a Javascript Calculator decimal issues

Hi! I’m having some issues with this project

My code isn’t able to pass the 11th test

But when I do the same sequence, I get this on the display

It’s like on the test the decimal button is not working or something, what am I doing wrong here?
I figure that I should post my code here, but it’s a lot of stuff, should I put it in some pastebin and link it here?
Thanks a lot in advance!

Could you post the link to your code?

Sure, here it is

Damn I can’t figure out why this is happening
