<br>
I was looking at the definition of reals via Cauchy sequences in the<br>
HOTT book, and I wonder how tricky it would be to implement that within<br>
the hott-agda library.<br>
<br>
Given that it has not been done before (as far as I can tell) – is that<br>
because it is obvious and trivial, or because it is known how to do it,<br>
and just tedious, or is it because it is expected to be challenging?<br></blockquote><div><br></div><div>I don't know if you already found these, but just in case you haven't seen them:</div><div> * <a href="http://www.cs.swan.ac.uk/~csetzer/articlesFromOthers/chiMing/chiMingChuangExtractionOfProgramsForExactRealNumberComputation.pdf">http://www.cs.swan.ac.uk/~csetzer/articlesFromOthers/chiMing/chiMingChuangExtractionOfProgramsForExactRealNumberComputation.pdf</a></div><div> * <a href="http://www.cs.nott.ac.uk/~nzl/Home_Page/Homepage_files/%5BNuo_Li%5D%5Bfinal_year%5DReport.pdf">http://www.cs.nott.ac.uk/~nzl/Home_Page/Homepage_files/%5BNuo_Li%5D%5Bfinal_year%5DReport.pdf</a></div><div><br></div><div>Jason</div></div></div></div>
