Question about Value Set Conversion

Hi, could someone explain to me what is a value set? I'm reading JLS Third Edition chapter 5.1.13 and I don't understand what the following is:

1) float-extended-exponent value set

2) double-extended-exponent value set

3) float value set

4) double value set

Since I don't understand the above I can't understand the main concept about Value Set Conversion which is:

[quote]

Value Set Conversion is the process of mapping a floating-point value from one value set to another without changing its type

Thank you for any help

Ah ok, I did go through it, but when I saw that any finite non-zero value of any floating-point type can be expressed in the form:

s * m * 2(<sup>e-N + 1) with the discussion which followed somehow I skimmed :)

At least now I understood the Value Set Conversion, which is the process of mapping one value set (let's say the float value set) to another value set (let's say the optional and implementation specific float-extended-exponent value set).
