How to reproduce:
1. Create a new 3D project
2. Navigate to Edit > Project Settings > Time
3. Observe the field "Fixed Timestep"

Expected result: By default, the field is set to 0.02
Actual result: The field is set to 0.01999999

Reproducible with: 2023.1.0a23, 2023.1.0b18, 2023.2.0a23
Not reproducible with: 2020.3.48f1, 2021.3.28f1, 2022.3.5f1, 2023.1.0a22

Note: The version before regression had a Time Project Settings window with more options, but this was reverted to previous options. The reversion of this decision might've been the cause of this regression.

Notes:

- overall the DrawFixedTimeAsFloat method just needs a rounding call to clean this up. It's not necessary, but it seems like it might be nice to have and this is such a simple thing to add (Assigning task to myself: I haven't worked in trunk in ages and I'm using this to re-learn the new process)
