Weight number changes after being set by user

[Shrinks99]

Firstly, thanks for open sourcing this app! It's quite nice :)

Describe the bug
When users enter a value for weight it will change after the value is set. Eg: When I enter 135lbs it changes to 134.99lbs. This also happens when I tried entering a value in kilograms though I had to add more decimals for it to change. If I had to guess what the issue is, I would say that the app calculates things in kilos and rounds them nicely which causes values entered in pounds to be rounded strangely. For what it's worth, I think the imperial system is very dumb but we generally use it for weight in Canada for.... some reason. 🙃

To Reproduce
Steps to reproduce the behavior:

1. Go to app Settings
2. Change the weight value
3. See error

Expected behavior
I expect the value I set to be the value that is displayed / used.
