Issue with reading analogue value

[samuelhj]

Hello
Sorry this is a bit stupid, but I can't figure out what I'm doing wrong.
I have a PT100 sensor I'm reading the temperature value from. The signal is 0-5V and the scale is -40°C to 100°C
Which gives me the formula:
(Tmax - Tmin) * (Uin/Umax) + Tmin
Or in this case (100-(-40) * (1925/5000) + (-40)
Which should translate to about 13°C.

When I try to replicate this in Guide I just get 0 out... I'm sure I'm just misunderstanding something with Guide but I've been stuck on this for quite some time now and really could use a second pair of eyes. (Note: I only want positive values, since hydraulic fluid shouldn't be at minus temperatures and it's just easier to send over CAN like this, hence the switch at the end)

I was just overthinking this, as usual. The solution was obviously to use scale, since I was trying to feed a floating point number with the blackmagic mathmetics. Sometimes it helps to just write about an issue and come back to it the day after. Hah.
So the problem was (which I didn't realise until I set up checkpoints to check what was going on) that I have a floating point number, which Guide (for some reason, doesn't support) which was throwing everything off.

But scale with highest value and lowest value along with my switch works fine. I feel like a complete dumbass after this.
