How to smooth a concrete garage floor

[DaveCWK]

I have a single garage attached to my house with a concrete floor - the surface is very rough and covered in ridges. They are quite large - for example a car jack does not roll over them at all when jacking the car up. I think there is a term for this finish but it escapes me right now. It is really uncomfortable to work on and very dusty.

Does anyone know how I go about smoothing it out?

I'd love a super smooth floor with an epoxy finish, like you find in warehouses.

Thanks all, lots to think about.
I was going to take pictures but the surface is exactly as those posted above by lewisco!

I did think about tiling, but surely if the floor is covered in ridges, when I jack on the tiles it is likely they will sag/crack as they will not be uniformly supported from underneath?

I think I'm leaning towards a screed/stopgap/levelling compound - especially as the floor appears completely level with the tarmac outside so raising it slightly wouldn't be a bad idea.

Lewisco - have you used a jack on that surface - is it as hard as the original concrete?
