I have added #ATS to the languages for which there is a solution to the #RosettaCode #ModularArithmetic task:
Modular arithmetic - Rosetta Code https://rosettacode.org/wiki/Modular_arithmetic#ATS
This task was practically tailor-made for #Ada. :) But ATS lets us easily extend the language to handle modular numbers.
#ATSlang #FunctionalProgramming #Proofs
Update: After reading the task language again, I added some more commentary, to point out what I see as a flaw in the task.
Now I have both enhanced the #ATS program (to show how to take advantage of the macro system) AND added a #Scheme program:
Now I have added #CommonLisp --
Now I have added #Mercury --
https://rosettacode.org/wiki/Modular_arithmetic#Mercury
#RosettaCode #MercuryLang #LogicProgramming #FunctionalProgramming
(For convenience I use higher-order functions, so that the Functional Programming hashtag makes sense. Also, Mercury is a language in which tail recursion is the preferred method of looping. And, it just occurs to me, I wrote the program mostly as ‘functions’ rather than ‘predicates’!)
I just keep going. It is a pretty simple task. I did more than was called for, in the #ATS example I did first.
Here is #Fortran --
https://rosettacode.org/wiki/Modular_arithmetic#Fortran
As with the ATS, I use a macro, although the macro system is not as capable as that of ATS.
(I used the C preprocessor. There was once a standard Fortran preprocessor, but it was removed from the standard. Nobody used it. Everyone used the C preprocessor, m4, or some such.)
I have added #ObjectIcon --
https://rosettacode.org/wiki/Modular_arithmetic#ObjectIcon
#RosettaCode #ProceduralProgramming
(I will not call this an example of #LogicProgramming, given that I never use goal-direction or failure in any significant way. But #ObjectOriented does apply.)
Lo and behold, now #OwlLisp (a dialect of #Scheme without anything mutable in it):
https://rosettacode.org/wiki/Modular_arithmetic#Owl_Lisp
#RosettaCode #ModularArithmetic #FunctionalProgramming #Lisp
Finally (at least for today), here is a second #Fortran program:
