To have unlimited precision is needed unlimited space...
There's no way to have unlimited precision for any number.
If you have n bits to represent some number, then you'll have 2^n
numbers represented. Or else you'll have two numbers being represented
in the same way, which would lead to ambiguity on the way back.
