>>11866594bitch, we both just copied arabs differently when it came to typesetting
Arabs used a mark between the ones and tenths place that started at the bottom and went straight down, sort of like a period that’s elongated vertically, or like a comma that’s not slanted. British used a period in its place and French/Italians used a comma.
Mathematics are far older than computers or the United States.
See picrel, blue is what you’re calling “universal”.
The specific symbol is called a period, not a decimal. You could use any symbol for it. And the computer simply acts as the programmer tells it to.
And spaces only have significance in European numbers the same way that commas have significance in ours.
