First of all, there are many differences attributed between CS1.6 and CS:GO. The most important thing to note is the engine; it's improved dramatically over the past 9 years (CS1.6 was released in 2003, CS:GO in 2012). Namely, CS1.6 uses the GoldSrc engine, which is a heavily modified Quake engine, and CS:Go uses the Source engine.
Second, CS:GO features drastically balanced gamemodes and weapons. Most notably, they completely changed the way Hostage missions worked previously in CS:S and CS1.6, and made it a lot more balanced for both sides. Some new weapons were added, and most of other weapons got a huge balance update (default pistols get a buff that puts them up to standard to other pistols, deagle nerfed).
Along with that, CS:GO also features a matchmaking system extremely similar to that of TF2, but it forms games based on a "combat rank", which helps to put similar players of similar skills in the same games.
Some other features are a complete UI revitalization, a more informative and easy to use buy menu, and an extremely polished user-friendly tutorial. Some minor things are the removal of flashlights (some servers have it with plugins), as well as getting rid of pre-defined loadouts.
Also included now are "weapon" skins, cosmetic variants of stock weapons that have no effect on gameplay but can do things such as track kill counts, be named as something else, etc.

1. What are float values?
Float values are the precise wear value of a skin. This value is a value between 0 and 1, where 0 is the least wear. The float values are mostly used in trading and trade-ups, and for most people the exterior quality is enough to know.
This is what the exterior on the skin is based on.
Note that not all skins have the full range of possible values. A AWP | Asiimov for instance, can only have values between 0.18 and 1, making

impossible.2. How can I calculate float values?
You can not calculate a skins float value, but it is possible to find. There are several services that can tell you your exact float values. Examples are CSGO Exchange and Steam Analyst.
In a trade-up contract on the other hand, you can calculate the float value of the item you will receive.
This is important if you're trying to "craft" a weapon. If the item you want has a full float value range (0-1) the formula is simple, its simply the average float value of all the low tier skin.
If your trying to craft a weapon that does not have the full float value field, the formula is somewhat more complicated.
