Hi,
To help me in learning Haskell I started blogging about some of the things I’ve
looked at.
One such topic was calculating square roots ‘by hand’ and then deriving a
Haskell algorithm.
I wrote about the well known technique here
http://gitcommit.co.uk/2017/08/25/the-root-of-the-problem-part-1/
<http://gitcommit.co.uk/2017/08/25/the-root-of-the-problem-part-1/>
and it it is really quite a simple method.
The second part of the post will be an implementation in Haskell.
I then tried implementing it and got something that works but really its not
very pleasant to look at! And its something I don’t want to post! Some parts
are fine but I think I locked myself into the notion that it had to be using
State and really the end result is pretty poor.
I know this i perhaps a ‘big ask’ but I’d really appreciate any suggestions,
solutions, hints etc. I will of course give full attribution.
I’ve created a gist of the code here
https://gist.github.com/banditpig <https://gist.github.com/banditpig>
Many Thanks
Mike
