How many types of grounds symbols in electronics?

There exist different kinds of grounds: chassis ground, earth ground, circuit ground, signal ground. My query (which consists of some related queries) for this post is about earth ground and circuit ground. I proceed with other queries once this one is settled.
Circuit ground is essentially a reference point to measure voltages at different points around circuit. Earth ground is used to protect human life from electric hazard and for this purpose third wire (yellow/green) is used to take back the current to the ground.
Do you think this power supply is dual polarity one? Don't you think to be completely sure one must refer to the manual/booklet which comes with the supply? I have once used this supply and its ground terminal is to be used as earth ground hence it cannot function as a dual-polarity supply. Would you refer to thissupply as a multi-polarity one?
Sometimes a term "floating ground" is used, what does it mean?
Please help me with the queries above. Thank you.
