Improve exchange rate calculation

[reneaaron]

I did test it with a waveshare2in13v2 display, other displays unfortunately remain untested.

Nice, its working! I think it will help to calculate a more accurate exchange rate.

I was a bit confused by the decimal place in the exchange rate. Especially since he sometimes shows one or two. Maybe one would be enough.

The first picture shows a calculation without the changes and the other two with the change.

I don't think it's related, but during the tests I saw an error message in the debugger. However, it came with and without the change. That's why I'm more likely to assume that it was the lntxbot again. But for the sake of completeness I would like to mention it.

Thanks for testing and your feedback @AxelHamburch! 🙌

I agree that space is very limited and we could just displace one decimal place as this is just an additional info for the user. The final amount will be calculated with the exact exchange rate, anyways. I'll update the MR.

[AxelHamburch]

Great! What do you think @lightisfaster ?

[reneaaron]

@AxelHamburch I still need to incorporate your feedback. 😅 I'll have the MR ready later this week.

[reneaaron]

@AxelHamburch I just updated the MR. Should be ready to merge!

Hey, looks good for me, i've test it too. Thanks for feedback @AxelHamburch. Good job @reneaaron and sorry for the delay. The alignment of the text may need to be adjusted for a display type, but this is trade off we can accept.
