What is the difference between floating and fixed voltage?..

For fixed voltage, (assuming you mean ground-referenced), one DC line or one AC phase (or neutral) is connected to ground (AKA earth).

The output of a floating power supply is isolated from ground/earth.

A floating voltage is generally produced from the output of a transformer, a power supply or a battery, unless the circuit powered is tied to a ground reference.

A voltmeter will not detect a floating voltage when measuring between the floating point and ground.
