Jeroen van Rijn	18dda6ff9d	Start of core:math/bigint ... We have: - `init` to create a new `Int` - `init(from_integer)` to create a new `Int` and set it to `from_integer`. - `set(Int, from_integer)` to set an `Int` to `from_integer` - `add(dest, a, b)` to add `a` and `b` into `dest`. - `sub(dest, a, b)` to subtract `b` from `a` and put the result in `dest`. And a few helper functions, like: - `is_zero`, `is_negative`, ... - `grow`, `shrink`, `clear`, `zero`	2021-08-11 20:59:50 +02:00
