I mean, why even bother with this shit langauge?

tl;dr, but I saved pic related for future use.

Who ever decided that javascript would be useful outside of the browser should be blood-eagled.

It's because they are too retarded to learn more than one language. The use meme words like "powerful" to justify their bullshit.

almost every language has that...
you don't understand the beauty
node is the language of the future

>Using floating point for small fractional numbers

I don't believe you exist.

I don't have enough palms to do do a facepalm that would do this justice.
It's been some time since I've met a person who doesn't understand IEEE-754.

people like me are the majority
before i used to program in various languages ranging from C to lisp but when i first seen JavaScript i quickly realized that all other languages are pure shit, while javascript is absolutely beautiful

he's meme'ing, m8

fuck you, js isn't a meme

JS is objectively shit with more shit stacked on top of it, but that's not how floating point numbers work.

I'm actually impressed that out of all the retarded behaviours of the language, you chose to be TRIGGERED by the one that actually is supposed to act that way.

This being said, I can't fucking wait for web assembly.

This is my personal favorite "bug" in JavaScript

It is kind a nice to be able to write both front and back end with same language, but it's pretty much strictly for web stuff. I wouldn't use javascript anywhere else.

Now that I think about it, I probably wouldn't be using nodejs anymore. It was nice at the time though.

Man, the type convertions, the rest are also funny
>> [] + []
< ""
>> {} + {}
< NaN

Why would I want javascript to use fp64? Heck I don't even want it to use fp32.

does javascript really need 64 types?

Even fp64 won't save you here. It's impossible to precisely represent 0.1 in a binary format in a finite amount of memory. It's the same case as 1/3 in decimal.

>It's impossible to precisely represent 0.1 in a binary format in a finite amount of memory

MIT Nigger detected. Its easy, you represent it as a fraction (two integers) instead of a decimal.

This.
Seriously, do you even know, how floating-point numbers are stored in modern machines? Read about fast inverse square root and educate yourselves.

what does fast inverse square root got to do with this? are you just trying to sound smart?

How are you supposed to test for equality with floating-point numbers? Check if it's within a margin of error?

>equality operator
>floats
Found the pajeet retard.

Yes. NEVER EVER use the equality operator on floats.

This is a floating point problem not a language problem.

Use tolerances / approx equals

what do those arrows on the left denote?

returns

whoa

document.write(Array(8).join('wat' - 1) + ' Batman!')

you guys have the entirety of javascript to make fun of and you choose its inheritance methods and fraction precision
i don't get it

JavaScript sucks and I hate I get paid so much money to write in it.

>subtracting 1 from string
What's the prototype?
You don't understand its beauty

> 0.30000000000000004


bruh
