*Arithmetic in Python V3*

Hello, hello! Our latest Python tutorial is on arithmetic in Python V3.  The main difference between V2 and V3 is that whole number division in V3 returns the correct value as a float, while in V2 it returns the quotient.

More videos are coming soon!

I'm impressed how clear you made this topic.

At 1:10 it is stated that the float is rounded then made into an int. This is incorrect, the float is truncated then made into an int, as such using int() to convert 3.2 or 3.8 will return 3 and -3.2 or -3.8 will return -3. Which is consistent with normal integer arithmetic.
To round and convert you must use round()[yields 3, 4, -3, - 4],
for more control import "math" and use math.ceil()[yields 4, 4, -3, -3] or math.floor() [yields 3, 3, -4, -4]
Also to get [4, 4, -4, -4] using the above inputs: int(math.copysign(math.ceil(abs(g)), g))

This makes me want to watch Stargate..
great videos

[fernandosuyama]

Awesome videos! You can add exponent operator **, for example: 4**2 = 16

[Etronic]

that`s very clear explanation, thanks for that. But to add some tiny correction in 1:12 " yo said the number first rounded then made it to an int. and as the round() is a function which convert the float number to the Nearest whole number and different from int() casting function, its better to say Not first rounded. thank you

Appreciate the effort you guys put in :)

[kiranshah]

Your python tutorials are awesome !!!

It will be better if you will share the slides for this playlist ....Please ...

Thanks in advance

[MrPurush]

good presentation easy and simple to understand .

[AlexMaday]

The int() constructor doesn't round, but truncates

[AhmedAhmed-nfzg]

i love you, you oped to me new world thanxxx

[jackyoung]

Why do we have to make a integer “wider” in order for the integer to operate with a float?

[captainfuture]

I don't understand why this channel has few viewers. It seems people don't want to learn programming.

[Bhavishtraders]

MY question is why we cant convert complex numbers into floats ? like DUh just add -0j in the complex number you will get the float back simple logic. pls reply

[deniszest]

then you making int of a float it`s NOT rounded it`s rounded DOWN or decimal part is Discarded

[pastorofmuppets]

sheesh i just started learning python and im already terrified

[ulilulable]

Another "interesting" difference between python 2 and 3:
python3: (2+2j)//2 -> TypeError: can't take floor of complex number.
python2: (2+2j)//2 -> (1+0j) # seems like they only truncated the real part

[krish]

when int is used with a float number, the fractional part gets removed, THEY ARE NOT ROUNDED OFF, AS MENTIONED IN THE VIDEO...

[orangerazzz]

Im using windows when following this tutorial. And I dont get the Ellipsis after a # comment line Anyone know why?
