math/big: handling of +/-Inf and zero precision, enable zero values
- clarified representation of +/-Inf
- only 0 and Inf values can have 0 precision
- a zero precision value used as result value takes the max precision
of the arguments (to be fine-tuned for setters)
- the zero precision approach makes Float zero values possible
(they represent +0)
- more tests
Missing: Filling in the blanks. More tests.
