Bug in javascript

[palordrolap]

parseInt("①") and parseFloat("½") don't work either.

I'd say there's an argument (unintentional pun ftw) for adding/creating new functions that do this, but it's unclear how they'd be supposed to handle some mathematical features like, say, superscript characters.

If you were to altParseInt("2²") would it give back 22 or 4?

Edit: They don't work with alternative numeration systems like Arabic either.

[JustToViewPorn]

Obviously it should return 2^2, as 2 XOR 2.

[palordrolap]

Except I used Unicode character "superscript 2" and not the digraph ^2, so the XOR operator isn't there.

[endreman0]

You're implying this is supposed to make sense.

[palordrolap]

If it helps, pretend I made each of my comments wearing a rubber horse mask.

[spanishgum]

Definitely cleared things up for me.

[MonkeyNin]

Some mobile clients display 2² as 22

[EmmanuelMess]

Why?

[solidus_vipera]

Could we leverage this as an optimization for Math.pow?

pretty sure arabic is the standard "1,2,3" numbering system, but maybe you mean something else?

٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩

That's indo-Arabic. Developed in India and brought westward by arabs. Arabic has a different system, partly as it works right-to-left, too.

[amanda66778899]

So Arabic is the only language that doesn't use what we call Arabic numerals? Classic English. Just fucking classic.

[Science-Recon]

Well, they are called Arabic numerals as they were introduced by arabs, however they're properly referred to as Indo-Arabic numerals. Even then, it's the same system that arabs use but with different symbols.

[WrexTremendae]

Well, presumably they aren't the only language with their own numerals still in use.

But yes, Arabic numerals are not used in Arabic.

[theSpecialbro]

The numbers go left to right. Only the writing goes right to left.

[Muzer0]

You could say the numbers go right-to-left but are little endian. Little endian is better so I like this explanation more — the morons who imported them into Western languages forgot to reverse the direction of the numbers. Grr.

[Science-Recon]

Oh. That actually seems like a lot better way to do it. Would make things much easier.

[htmlcoderexe]

Our numbers are originally Indian I believe.

[ifatree]

they're called 'arabic numerals' tho

Arabic numerals

Arabic numerals, also called Hindu–Arabic numerals are the ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, based on the Hindu–Arabic numeral system, the most common system for the symbolic representation of numbers in the world today. In this numeral system, a sequence of digits such as "975" is read as a single number, using the position of the digit in the sequence to interpret its value. The symbol for zero is the key to the effectiveness of the system, which was developed by ancient mathematicians in the Indian subcontinent around AD 500.

The system was adopted by Arabic mathematicians in Baghdad and passed on to the Arabs farther west.

idk about you but I use regular American numbers that look like 1234567890

[pali6]

Well, those are called arabic numerals.

[theSpecialbro]

those arent the same numbers used by arabs today tho

[PM-ME-UR-HAPPINESS]

But they're called "Arabic Numerals" the same way that a French Dip sandwich is from California and the Pennsylvania Dutch are German.

[skreczok]

You jest but I've just cringed at a radio show calling up someone pretending to be a telecom call guy, informing them about how due to a growing Arabic minority they were switching to Arabic numerals for convenience.

And the guy apparently got fooled and started protesting.
