OK. When you say "arbitrary precision," you mean that a precision limit must be set (at run-time) before an operation. Most people use "arbitrary precision" to mean unlimited precision, not your "run-time cut-off" precision.
Are there really libraries that have unlimited precision? What happens when the result of a computation is irrational?
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.
