Maybe it’s discussable and I don’t know how long it exists, because variable things often change and I’ve seen in the future new created variables will be default type Number instead of String…
But I think it’s a bug if that
doesn’t make this condition true and I have to use “0”
If I later want to make a variable empty, I also have to fill it with “0” or use two different conditions or set it to “” at the beginning to remove the mysteriously internally created 0. For years I’ve more often been a bit confused about how GD handles empty variables, default, for different types…
