Then I notice the labels under the time line were also floating point numbers. Is there a reason for the frames being in floating point numbers?

Right mouse click on the play controls and you will see a menu with how many frames or half frames to to move with arrow keys. Choose 0.5 and use arrow keys to move half a frame, or subframe. This can be useful for rotoscoping or some effects where you need that kind of precision. Maybe compositing gunshot wounds or muzzle flashes etc. Or manual roto adjustments of very fast objects. Or if you want to skip ahead, say 10 frames at the time.

I don't know if you have to use float numbers for your footage for this to work or not, or some setting in the preferences, but for me it works.
Manual says this:
Frame Increment Options
Right-clicking either the Play Reverse or Play Forward buttons opens a contextual menu. This menu contains options to set a frame increment value, which lets you use a keyboard shortcut to move the playhead in sub-frame or multi-frame increments.
Moving the playhead in multi-frame increments can be useful when rotoscoping. Moving the playhead in sub-frame increments can be useful when rotoscoping or inspecting interlaced frames one field at a time (0.5 of a frame).
