Numeric datatypes built from scratch
As a self-development exercise, I re-implemented some numeric datatypes without using any of the implementation language's underlying numeric datatypes.
I chose Ruby for this, partly because I haven't written anything in Ruby for ages, and partly because its mixins/inheritance model make parts of it a little bit easier.
At time of writing, this endeavour includes:
- A natural number datatype,
Counter, which represents numeric values as nested lists - An integer datatype,
Dint, which represents a signed integer as an object with a positive and negativeCountercomponent
Mijn verontschuldigingen to any Dutch people
reading this. This exercise a sequel
to "Swiss numbers", which implemented the standard
arithmetic operators in terms of +, and which
were nowhere near as impressive.
