Talk:CRC-32: Difference between revisions

I don't quite understand the reasoning/logic behind the test program:

: if the program gets a SYNTAX error ''anywhere'', it counts as OK.

: if the program successfully does the two '''D2C'''s, it counts as an error in one case, but not the other.

: if the program successfully does the 2nd '''D2C''', it is counted as an error.

: no check is made to verify that the value of '''D''' matches the value of the 1st argument (999999999).

A     '''parse version x; say x'''     was added after the 1st statement.

<br>A &nbsp; &nbsp; '''say 'digits=' digits()''' &nbsp; &nbsp; would be a nice addition.

 

::: The word I used was ''innoxious'', not ''obnoxious''. &nbsp; Also, I believe it's considered bad form to change people's quotes (I don't mind the correcting of an obvious misspelling, but not the content) --- especially on the discussion (talk) page. &nbsp; The reason I had the various flavors of Regina listed was that some Regina versions were considering numbers as integers that may or may not be considered integers, &nbsp; i.e.: &nbsp; -.1e7 &nbsp; and &nbsp; 12345678912345 &nbsp; for instance. &nbsp; I don't know where Regina REXX currently stands on this. &nbsp; There was some discussion of this topic in the newsgroup '''comp.lang.rexx''' a few months (or maybe years) back; it had to do with what a user expected (REXX's principle of least astonishment) versus what the REXX standard stated &nbsp; (in both examples, both are clearly integers, but maybe not so much according to '''numeric digits'''.) &nbsp; I used the word ''integers'' instead of ''whole numbers'' 'cause some people where saying (in the newsgroup) that negative numbers weren't whole numbers, and some also stated that zero isn't a whole number. &nsp; Sheesh! &nbsp; ''Natural numbers'' and ''counting numbers'' were also thrown around rather loosely. &nbsp; It was a lively and animated discussion as I recall. &nbsp; Walter, if you're going to add your comments interspersed within my signed comments, please sign your inserted statements. &nbsp; It appears that I'm contradicting (my bullet points) with myself and it's not clear at all who is stating what. &nbsp; Also, now that the REXX program has changed drastically, my (REXX) output no longer matches anything posted, so the results are meaningless. &nbsp; That's what programming versions are for (version 1, my output; version 2, ...). -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 18:52, 18 August 2013 (UTC)

 

::: So Regina would not have passed my test suite. Time to ask for Regina's POV (which I will do when I am back home) --[[User:Walterpachl|Walterpachl]] ([[User talk:Walterpachl|talk]]) 09:09, 18 August 2013 (UTC)

 

Perhaps this discussion would be better served where there're more (varied) REXX experts (and REXX authors) around --- [such as the REXX newsgroup, '''comp.lang.rexx''']. -- [[User:Gerard Schildberger|Gerard Schildberger]] ([[User talk:Gerard Schildberger|talk]]) 19:00, 18 August 2013 (UTC)
