It kind of sucks that this side of his content doesn't get a lot of attention, i really liked these videos and it helped me a lot to understand basic programming concepts. Same with Michael Reeve's programming tutorials. (Yes, he did those, like two or three videos i think.) Jabrils will forever be my major programming inspiration.
I just discovered your page today and I just want to thank you! I moved to a new technical sales role but I had no background in development. Your videos have really helped me figure out a few things. Really grateful. Keep you the good work!
What is the difference between a float value and a double value? In my hi school i learnt double and in my own time and projects i use float, so what is different between the two
Size difference, in most languages *doubles* are twice(double :) ) the size of a *float* , therefore they're more accurate, they can have more digits than floats. I believe a float has 7 digits and a double has 15 digits
@@thelandoftwitchclips English is my second language, but thanks for being so kind as to point that out, may I ask where my grammar mistakes are and what I should've wrote instead
there might be some weird workarounds. generally, if you work with floats then the floating-point error is going to be there, but it is usually precise enough to not matter. If I remember correctly then you could define your own "Floating-Point" data-structure when stores the decimal places in an array, but there are almost certainly better ways.
Its a pity (shame?) you could not talk about precise floating point calculations in python... Often calculating with float to get as most accurate result as possible is crucial. Also, you could show how to print certain amount of decimal points after calculation
0:42 BIG MISTAKE. we know exactly how many decimal figures pi has: an infinite number of ‘em. infinite doesn’t mean we don’t know. infinite means infinte. please excuse me, i’m a mathematician xD
I mean....We all knew what he meant: we don't know all of pi's digits. I don't think it's a big deal really, not like it's going to effect anyone's code, but I understand. Also, why do you like math so much? Just the beauty of math or it's power in solving problems?
Short answer: float = decimal number
1.45 = float
1.84628473 = float
2 = integer (not float)
2.0 = float

This is the best tutorial on youtube
hands down
Thank you for your time Jabrils! Great Video man!

According to google a double has 2x the precision of float(however it also requires more memory)

@@ostro7941 "i learnt" is "i learned" as far as i can see, english is my 2nd language too
I used a = a + 5 before this! Thank you!
Yes...
I don't understand floats. They go over my head.
do you mean they float over your head?
Yes...
So is there a way to fix the 7.77 - 3.33 in python? what if i wanna make a calculator

@@EndyStar rounding sounds like the worst solution for a calculator
i'm having trouble trying to read a float value from the user in C#, can someone help me?
wouldn't it be like "float a = input()"?
i don't do c# but i guess it's something like that
Wait, how to use float in games? Is it like determining maths like in game currency?
how to make float array?
Nice 👍
i want to learn beacuse i want to have a coding job
Me too!

A mathematician that still says "xD" mmk
SuperSuheb which is not true either...
please jabrils study a little bit of algebra!
