[BUG] "Greater than" node is wrong

Hello,
For some reason when I use the “Greater than” node, I get invalid results and I can’t get my head around why it happens. I tried floor values instead of floats but both have the same problem.
Any idea? Seems like a bug to me but I’m not sure…

Probably the same as this:

You’ve got some kind of random node on the left, yes?

Sometimes there’s a bunch of similar questions coming in waves. I always wonder if this a school assignment.
