I am curious to know how you are so certain it is the floating type? At the NAPA parts store, I saw both types with no clear method how to distinguish which was installed.

I did remove the retaining clips and did soak thoroughly the seam between the rotor and the hub several times over the afternoon. With a hammer, I hit on the backside of the rotor rotating it 30 degrees and hit again. I did this many times but was cautious not to hit it very hard. Until I can be sure it is the floating type, I did not want to really hit at it hard. I can certainly see how it can be siezed to the hub.
