I added #OwlLisp to the repertoire of my answers to the #ContinuedFractions arithmetic draft-task on #RosettaCode:

Continued fraction/Arithmetic/G(matrix ng, continued fraction n1, continued fraction n2) - Rosetta Code https://rosettacode.org/wiki/Continued_fraction/Arithmetic/G(matrix_ng,_continued_fraction_n1,_continued_fraction_n2)#Owl_Lisp

#scheme #lisp #FunctionalProgramming

I translated, from #Mercury to #Haskell, the #ContinuedFractions #RosettaCode draft task:

Continued fraction/Arithmetic/G(matrix ng, continued fraction n1, continued fraction n2) - Rosetta Code https://rosettacode.org/wiki/Continued_fraction/Arithmetic/G(matrix_ng,_continued_fraction_n1,_continued_fraction_n2)#Haskell

I have decided there isn’t a single thing I like about Haskell syntax. I do not care how one writes a thing, I hate it. There is no reason whatsoever for Haskell not to have had a more ML-like syntax. None whatsoever, except to encourage breakage.

An implementation of the #RosettaCode #ContinuedFractions arithmetic draft task, in #Mercury, based very loosely on the #StandardML (that is based on the #Scheme and the #Python:

Continued fraction/Arithmetic/G(matrix ng, continued fraction n1, continued fraction n2) - Rosetta Code https://rosettacode.org/wiki/Continued_fraction/Arithmetic/G(matrix_ng,_continued_fraction_n1,_continued_fraction_n2)#Mercury

The implementation uses #LazyLists to represent continued fractions.

The #StandardML was a particular pleasure to write:

Continued fraction/Arithmetic/G(matrix ng, continued fraction n1, continued fraction n2) - Rosetta Code https://rosettacode.org/wiki/Continued_fraction/Arithmetic/G(matrix_ng,_continued_fraction_n1,_continued_fraction_n2)#Standard_ML

#SML #RosettaCode #ContinuedFractions

I have now done the #RosettaCode #ContinuedFractions arithmetic draft task in #Ada --

Continued fraction/Arithmetic/G(matrix ng, continued fraction n1, continued fraction n2) - Rosetta Code https://rosettacode.org/wiki/Continued_fraction/Arithmetic/G(matrix_ng,_continued_fraction_n1,_continued_fraction_n2)#Ada

I credit my own Python implementation as the original, although the Ada is quite different. Interestingly, I use ‘inheritance’ in the Ada but not in the Python! One might ask why ...

#adalang

This took a few days of overwork and obsessive overexcitement to write. A #Fortran port of my #RosettaCode for #ContinuedFractions, including a primitive #MultiplePrecision module:

Continued fraction/Arithmetic/G(matrix ng, continued fraction n1, continued fraction n2) - Rosetta Code https://rosettacode.org/wiki/Continued_fraction/Arithmetic/G(matrix_ng,_continued_fraction_n1,_continued_fraction_n2)#Fortran

Part of the problem, as I have mentioned before, is that gfortran is not especially helpful in tracking down bugs. But I see gdb has gotten better with Fortran.
