All numbers in Javascript are so-called 64-bit double-precision floating point numbers, that are decided by 64 bits. Bit 0-51 decides the fraction, the exponent is 52-62, and the last bit is a boolean check (0 or 1) to see if it's signed or not. A signed number cannot be negative, so it essentially doubles the maximum positive value while removing all negative numbers. Since numbers are stored like this, as binary fractions with exponents, both 0.2 and 0.3 cannot be accurately represented (because the machine runs out of memory because it repeats itself infinitely, just like 1 divided by 3 is 0.33333... forever), so an internal routine is run within the programming language to fix this, rounding the answer to the closest representable 64 bit structure. 0.2 is represented as "0011111111011001100110011001100110011001100110011001100110011010". Where the first 0 represents signed/unsigned, the following 11 digits representing the exponent, which is binary for 1021, and the following 52 digits represent the mantissa, or the fraction. This is the closest you can get to representing what 0.2 is in Javascript, but it's not entirely the same. 0.3 works similarly.

python is the best for, litteraly everything, even 3d game developement, easy to use, lots of libraries and tool, can easily access internet, can download wideos from anywhere even from youtube without any premium, cqan open apps in your computer, in extensions has lotťs of powerful AI helpers and game developement is too easy, that makes the python the best language, ofc its good to know Java, C++ too, but if you want to get paid great learn python

kids who are saying scratch is not for kids and I can earn from that, it is for kids and nobody will accept you to work with scratch

Noooooooooooooo-tion

Haha don’t doesn’t have to do with binary

Racket 😍

Don't shill for ozempic

If I say I have already seen this coding question. I may miserably fail the next coding question and they will throw me right away. 😅

Javascript is so stupid it became quantumly stupid

What's the woman's name?

I would be disowned if I learned Java or JavaScript. This is probably already knowing too much.

I want a epic rap battle between you and fireship Firebase vs Clerk 🤣

You know how 10/3 can’t be written in decimal because it’s 0.333333333…? Well 3/10 is like that in binary

I’m seeing this video just after learning some basics of HTML. Should I make an immediate switch to python?

Schroedinger's null

Actually the Polar Express Nerd was wrong: the loconotive wasnt the 4-8-2 Baldwin S3 but the #1225 Perre Marquette Steam Engine 🚂🚃🚃🚃🚃🚃❄️❄️

She doesnt move on bro😂

What a chad

bro what is this video!!! I love it!!!

ok but waterloo cs is extremely hard to get into in the first place... so you're clearly competent

Please upload the rest of this series

Tells us he'll explain the answer..... then never explains the answer.... He'll be a perfect lawyer

Get gud

I love everything about this😂

Now type 1*1 and make it = 2

Super insightful. Clerk seems like a game-changer

This has nothing whatsoever to do with JavaScript. Try C++ you'll get the same answer.

WELCOME! HERE YOU GO: In JavaScript, due to how floating-point numbers are stored and calculated, `0.1 + 0.2` might not exactly equal `0.3`. It could result in a very tiny difference due to precision issues. This is a common quirk in many programming languages when dealing with floating-point arithmetic. Q: wtf is floating-point arithmetic? A:Floating-point arithmetic is a way computers represent and perform arithmetic on real numbers with a fractional part. It's called "floating-point" because the decimal (or binary) point can "float"; that is, it can support a varying number of digits before and after the decimal point. However, due to limitations in how computers represent numbers, there can be small errors in the results of arithmetic operations, especially when dealing with numbers that can not be represented exactly in binary. Q: So the problem is with the computer, not me? A: Exactly. The issue lies in how computers represent and perform arithmetic with floating-point numbers, not with the mathematical concept itself. In the real world, 0.1 + 0.2 does indeed equal 0.3, but due to the limitations of representing real numbers in binary format, the result might not be precisely 0.3 when computed by a programming language like JavaScript.

Where did the 4 come from?..Oooooh. 304😂

Worked together with someone who did 3 years of Mathematics, his job? Moving a box 1 pixel to the right and adjusting the right color of gray for lines in CSS.

If sahil and Jason were alike in smarteness... why wasn't sahil an elephant? Like the dude left his job and risked everything for the full time microsoft job... Without even watching this video... Means that the fundamental person of Jason's job success... was sahil because he felt adventurous... or wouldn't jason be still overthinking that "God, i feel so fking stupid, ugh!" if sahil didn't take the first step to fall right into the risk... jason wouldn't have too. That also means that the quote which is quoted by mums "If your friend falls off a bridge will you too?" is actually a good thing.

I've been programming for more than 5 years. I've been trying to change my job for about 6 months, and I haven't gotten one interview since. I used to get interviews every month, I don't know what's going on in the world anymore. I'm glad that I have a job though, I would lose my mind if I didn't

I NEED HELP Im 13 and im trying to into programing but I cant figure out how to download java or python if someone can reply with a link to a video on how to download it or the website to download it its self please help

"Build something that people could actually use", love it. That is how I found your channel. I need to learn how to code, your channel has a ton of valuable information. I have patented something that is "something people could actually use" and just need to build it myself or get some help seems to be more the path after seeing your videos : ). I have used this patented idea in the workplace and have increased my productivity by 65% and out preformed my counter parts. Thank you for your guidance and videos. I am now a subscriber.

I touched a very tiny bit of Scratch and BASIC in 10th grade, learned a few basics in Python after leaving High School, then started learning C when i started 2nd year of University in my Computer Engineering course (last semester) (and really only coded in all of these, never programmed) and now i jumped to Rust, and have really only ever been coding 😢 Any advice?

That's not the right answer, pretty boy. My Linux machine's scientific calculator gives: 0.3... don't tell anyone where you went to school...

bro could've just said he doesn't know why

C++ all the way

Some day i wish i could just stardew valley life

I have always used Mathematica to avoid those types of numerical issues solving PDEs with moving boundary conditions when 16 decimal places is not enough.

As a previous react native developer I feel pain watching this video more than I'd like to admit.

No it's not a child knows why ! Devide 1 by 3 the answer is 3.3333333 , the same in reverse , the 00004 is the rounding up of .00003 recurring !

Because there is no .3 in binary

So funny!!!

sending yourself random shits on facebook messenger is so relatable

I want to learn to code because I want to make a cool app or an AI

☠️

I hate to admit it, but... that makes sense to me, intuitively.

This is my doctoral research 🧐
