Rounding error in Log Glucose entry (and possibly elsewhere)

[bjornoleh]

Describe the bug

When entering BG values in the Log Glucose screen, there is rounding applied at the time of entering values. This gives the wrong result sometimes. Confirmed for when entering the value of 9,2 mmol/L, which is immediately registered as 9,1 mmol/L.

To Reproduce

Steps to reproduce the behavior:

1. Set BG units to mmol/L
2. *Go to History / Glucose tab
3. *Click on Log Glucose +
4. *Enter 9,2
5. *See the New Glucose value being entered as 9,1

Expected behavior

Duh :-)

Trio Version:

• Version Number: [e.g. 0.2.0]
• Repo: nightscout/trio
• Git Reference: 6433d94

Technical Details

*Built to phone, but should be easily reproducible in any setup

I'd expect there to be more instances of this rounding error, but did not look for them yet.
