.float is a field float. This means every entity has its own variable float value you can set, such as health. You use it like: self.mydotfloat = 1;

While a float is a global variable, it is not different per entity. An good example is the float time; This does not mean it cannot be changed, it just means its accessible across all functions.

These rules apply for any data-type you use as a .type or not. (.vector .entity .string)

In your example there is no difference in the code, however many use the first example as its more readable and if you have multiple tests like that it is significantly easier to just change the 1 variable than all of them.

The reason is not exactly visual. Using constants makes code easier to read and to change (can you imagine someone using "4096" instead "IT_MYNEWWEAPON" in a mod and later discovering that needs to change every occurence of "4096" because it's the value of the already existing "IT_AXE" ? ).
I know FrikaC made a cgi-bin version of the quakec interpreter once and wrote part of his website in QuakeC :) (LordHavoc)
