Its main advantage is reducing the pressure on weak or compressible soil, thereby minimizing differential settlement of the structure built upon it.
No, it is economically and technically unnecessary. Floating foundations are designed for poor soil conditions where digging to bedrock is impractical.
In most technical contexts, yes, they are synonyms. 'Raft foundation' is a very common alternative term.
