Whammy Bar Tremlo

What is a “Floating Tremlo” on a guitar?
Is it like a Whammy bar that goes both ways, or a trem that isnt connected to the guitar like a normal bridge or what?
The floating tremolo was designed by Fender for the Fender Jazzmaster, and first appeared with the release of the Jazzmaster in 1958. A larger, heavier and more complex mechanism than the synchronised tremolo, and promoted over it by Fender as their premium tremolo arm mechanism, it never achieved the same popularity, though if properly set up according to Fender’s recommendations, it held tune as well or better than the synchronized vibrato unit.
The main difference is that, while much of the mechanism of the synchronised tremolo including the springs is accessed by removing a rectangular plate in the back of the guitar body, and is mounted on the guitar body in a routed bay extending behind the pickups, the entire mechanism of the floating tremolo is mounted on a roughly triangular chromed plate in the front of the guitar body, on the opposite side of the bridge to the pickups. The string tension is balanced against a single short helical spring, in compression rather than tension, mounted on the back of the tremolo mounting plate. The spring is adjustable by turning a screw located towards the center of this plate.
The ferrule ends of the strings are held on the top of the guitar in a tailpiece plate called the knife plate which emerges from the mechanism, rather than the strings vanishing into the mechanism as with the synchronized tremolo. It is the knife plate that is moved when the tremolo arm is operated. Unlike the synchronized tremolo, the bridge is not moved directly by the mechanism, but only by the movement of the strings, and is allowed to tilt to accommodate this movement. This is called a floating bridge.
