CS people what do you call // ?

[ehproque@neopaquita.es]

@futurebird but then I can't just divide an int by it and get the result into an int!

[amenonsen@mastodon.social]

@futurebird Darn, I just clicked on reply and didn't see that n people had already said the same thing. Sorry.

[ehproque@neopaquita.es]

@futurebird I'd have to do // but the text turns grey when I do that!

[darkling@mstdn.social]

@futurebird I'd call it an integer divide, I think.

[bencurthoys@mastodon.social]

@futurebird I'd say "division with remainder" if explaining it to a child. "Sixteen divided by five is three remainder one".

But my first computer - a BBC Model B - had DIV and MOD operators

and I was comfortable using them towards the tail end of primary school.

@ehproque @futurebird I'm an astronomer. Let's call it ten for now...

[khleedril@cyberplace.social]

@futurebird I have no idea what this even means, but I call it "Slash, slash."

@khleedril @futurebird I'm a quantum physicist, let's call it 1

You and the whole fifth grade.

@futurebird Comment?

*ducks*

[llewelly@sauropods.win]

@futurebird in all seriousnessness, the use of "floor divide" implies the result is rounded towards negative infinity, in contrast with "trunc divide" , which implies rounding toward zero, an important distinction when one operand turns out to be negative. Now here's a question: in your favorite languages, which way does integer divide behave? Does the language definition even require a particular behavior? (C90 and C99 for example call it "implementation defined". )

[jhominal@mastodon.social]

@martok this operator has returned an int since it was added in Python 2.2, so this seems weird?

[dalias@hachyderm.io]

@futurebird Jokes aside, is it a floor or a towards-zero like the awful C "division" operator? That would affect proper naming a lot.

[david_chisnall@infosec.exchange]

@futurebird

I can't read this and not interpret // as a start-of-line-comment marker. So this line is just 16. And I call 16 an integer.

[martok@mstdn.social]

@jhominal Only if both arguments are int. If either is float, the result is float even if its value is by definition int-ish.

I still think this violates the Principle of Least Astonishment, that's why I just don't use it anymore. int(a/b) is not that much more typing.

@ehproque

I still like to...

#define PI 3.14159265358979

it feels artisan. bespoke. handwoven

[jonathanhogg@mastodon.social]

@futurebird Years ago I got offered "show your Python skills" quiz on LinkedIn and the answer to this question was given as "integer division". I was so furious I put in a complaint. It is, of course, "floor division". And Python-style modulus is the One True '%' operator –C's remainder can get in the bin.

@yonder @ehproque

no no no THIS is "hand crafted" ... only the finest pi made of the most dubious loops.

import random
import math

inside=0.0
resolution=60000
for i in range(resolution):
x,y = random.random(),random.random()
if math.sqrt(x*x+y*y)<1:
inside+=1

pi=4*inside/resolution

print(pi)
