Rounding numbers, weird behavior

[RedWheiler]

I’ve a couple of sensors that acts weird while they got round to 1 number behind the comma.

I’ve no idea why at some numbers it gives me some strange outcomes…

Any ideas?

I think this answer might explain and solve the problem, Template: round(2) only works occasionally (or: seconds to minutes and/or hours?)

Thank you for pointing me in the right direction.
