Fuck whoever invented octal literals with just a zero prefix. 042 should never not equal 42. How hard is it to have 0x42 for hex, 0b11 for binary and 0c42 for octal

Oh, fun with number systems...

I remember scripts failing on 01.01.2008 because someone used some numeric constants with 0-prefix for years in the date calculation.

That was fun.

@irene Because that's how decimal works and nobody in their right mind thinks that you can't put zeroes in front of a number

At least dates are cool.. No wait forget what I said

0-prefixed octal literal have been deprecated in JavaScript. The syntax error only occurs in strict mode for backwards compability.

@irene Not only do decimal numbers work that way, all numbers in positional numeral systems with a zero work exactly like that

@Demolishun JavaScript, PHP even Java

@irene 0*10^2 + 4*10^1 + 2*10^0. No special case

@irene That's how this sorta number system is defined. 00042 is a completely valid number, exactly like 0.42000 is a valid number

@irene Yes. Are you honestly in defense of this retarded ass design flaw? 0c42 is more concise and more consistent

@irene What about trailing zeroes for decimals like 0.42000. Surely they're not valid either?

@irene https://en.wikipedia.org/wiki/... I'm just gonna leave this here...

Did I understand this conversation right?

@12bitfloat thinks that 042 shouldn't be an octal representation in any language but resolve to an integer instead (042 == 42) and octal should be prefixed with other characters than numbers, like 0c42.

@irene thinks that 042 shouldn't be a valid number in any base because same integer shouldn't have multiple representations (042 != 42).

If I understood correctly, I must agree with @irene.

@joas Not that it shouldn't be. It *is* a valid number. And it shouldn't be interpreted as octal but simply as decimal. Sometimes you want to zeropad numbers e.g. in matrix calculations so it lines up nicely. That's how I discovered this in the first place because my math functions returned the wrong results. 042 is a valid decimal number and there's absolutely no reason you shouldn't be able to use it as an integer literal

@irene Well that I don't agree with. In math decimal can have leading zeros, so it is definitely confusing if they were different base or different kind of numbers.

@irene If you are thinking binary format or value of an integer. You are right. There's no leading zero. And there shouldn't be. The value of 0123 is 123.

@irene I was talking about standard decimal representation in math not octals
