Incorrect display of wlan speeds over 1000 mbit

First of, great tool!

Onto the issue:
When the wifi speed is under 1 gbit/s it shows correctly as (let's say) 864.6 Mbit/s
When the wifi speed is over 1 gbit/s either the decimal point is misplaced, or the unit doesn't get updated from Mbit to Gbit: 1.0887 Mbit/s

Also, but I'm unsure if that's correct or not, the speed value displayed is only the "tx" value. The "rx" is ignored.
for example from the 864.6 Mbit speed screenshot, iw wlan0 link:
rx bitrate: 1253.9 MBit/s 160MHz HE-MCS 6 HE-NSS 2 HE-GI 0 HE-DCM 0
tx bitrate: 864.8 MBit/s 160MHz HE-MCS 8 HE-NSS 1 HE-GI 0 HE-DCM 0

Thank you so much for your help! You have a really fast wifi connection! I agree, the comma is misplaced.
I will try to recreate your problem, but I think my wifi is slower. Can I ask you where you got this information from?

rx bitrate: 1253.9 MBit/s 160MHz HE-MCS 6 HE-NSS 2 HE-GI 0 HE-DCM 0
tx bitrate: 864.8 MBit/s 160MHz HE-MCS 8 HE-NSS 1 HE-GI 0 HE-DCM 0

So far I used iwconfig for this information, but your data seems to be more detailed.

I'm using arch and it's this package:
https://www.archlinux.org/packages/core/x86_64/iw/

it's advertised as the replacement for iwconfig:

iw looks great! We should switch to that tool instead of iwconfig!
