How do #Arabic computer systems represent hexadecimal values if parts of the system use Hindu Arabic numerals? How would the set be extended to 16, similarly to how arabic numerals are extended with latin letters in the west.

@neauoire ive never seen this done. in practice hex tends to get represented using latin characters in my experience.

@nasser is the order of the characters reversed? I've seen this in the Arabic version of BASIC on the MSX but I couldn't tell from which side they were read.

@neauoire even in conventional arabic writing the direction of numbers is "backwards" relative to the direction of the text, so it wouldnt be jarring to an arabic reader.

@nasser omg! that's the system I'm looking at right now!! Wow, do you have an msx?

It's funny I was just talking to @256k about this very cart.

Ramsey Nasser

@neauoire @256k yeah!!! thats the one. i have a sakhr in my studio with a logo cart and now basic 🥳 no manual for the logo cart though, just guessing at commands lol

@nasser @256k Thanks okay, that's good to know. So if you were to represent a hexdecimal number in an arabic system and didn't have latin characters, what would you do?

Ramsey Nasser

@neauoire @256k its tricky because letters standing on their own are jarring to look at -- you really want them to join. then when they join youre going to read them as words. standalone letters arent really a thing in arabic and it extends to difficulties eg making acronyms (theyre very rare and the ones that do exist generally spell out a word)

@nasser @256k
Once you start poking with sakhr basic, I'd love to know if they say anything about hexdecimal modes for numerals in it. From screenshots I could find, it's always ever decimal, but I wonder if they extend the hindu-arabic numeric set, or it extends the arabic numeral set.

@neauoire @nasser I’m also really curious about this. Never saw Arabic hex mode personally. It feels weird thinking it would be something like ٣ت

@256k @nasser I'm more curious wether they use $7a, or $Ù§a

@neauoire @nasser ohh yeah I see what you mean. Considering the numbers on those screenshots are hinduarabic I’m guessing the latter. But yeah fascinating.
