i'm talking about biginteger being in some class/struct ghetto and not first-class like machine integers

he's talking about having to pull in a separate namespace (system.numerics) to use the BitInteger lib

but once you pull it in i don't recall it being any more difficult to use, don't they overload + and ++ and all that?

it's fairly new and i haven't really used it we use GUIDs in the one place i'd have a reason to use it

it's a feature so that $_GET['a'] == "2.0" works on a query string ?a=2. why that's a feature i have no idea but they won't remove it because that would break old code (hahahaha)

either you are a sperg who really doesn't understand why being able to compare those things is handy or are you just a disingenuous gently caress

Oh, okay. Well in Ruby FixNum (integers) actually silently fall over to BigNum so use Ruby.

i understand why trying to compare those things is useful but why would you write $_GET['a'] == "2.0" instead of $_GET['a'] == 2.0

Tiny Bug Child: Sep 11, 2004; Avoid Symmetry, Allow Complexity, Introduce Terror

you wouldn't, but stuff that comes out of $_GET is a string so $_GET['a'] == 2.0 would be false (or produce a spurious error) in type nazi land even if the query string was "?a=2"

I thought PHP was weakly typed. Or does weak type just means arbitrary decisions everywhere even for primatives?

use a long or a ulong. if u got integers over that big then they need a special interger storage mechanism.

i'm saying that the special integer storage mechanism is a pain in java/c#

like you can do

Java code:

int fart = 12345;
ulong toot = 4567890;

but you can't do

Java code:

bigint asdf = 4567890876543456789098765434567890987654;

and you definitely can't

Java code:

integer asdf = 4567890876543456789098765434567890987654;

instead

Java code:

BigInteger asdf = new BigInteger("4567890876543456789098765434567890987654");

in perl, you do == to mean 'do they look like the same number' and eq to mean 'do these look like the same string'.

as such, you don't get the ambiguous == 'can you mash either of these to look the same as a number, or are they the same string'

yes because there were also 0-based arrays unless you set an env var and then it was 1-based and oh god it was so bad

you can write an entire haskell program without seeing a type

i mean granted if you don't at least declare the types of your top-level declarations you suck but still

it's interesting that we are getting so much discussion from one little common programming issue. i think this is a good exercise; i like to see the different processes people follow even at this level.

for me it depends on the language:

1. google "compare [this type] and [that type] in [computer language]"
2. find ticked stackoverflow post
3. copy
4. paste

[...]
Java code:
BigInteger asdf = new BigInteger("4567890876543456789098765434567890987654");

it is both better and worse than it seems

in C# it would be:

C# code:

var adsf = new BigInteger(0)

if ( !BigInteger.tryParse("4567890876543456789098765434567890987654", adsf) )
{
 throw new BullshitException("lol this library sucks")
}

in java 8.0 or scala it would be:

code:

val adsf = BigInteger("4567890876543456789098765434567890987654")

all three languages have some type inference and are smart enough to get away from stupid C-style var declaration

but the c# system.numerics library is loving terrible, and the java.math stuff ain't so bad

c# is not a bad language but man are there some warts in that std library

but the point of the exercise was to show that c# is non-stupid and has some type inference so you don't spend time typing the type twice

it's not duck-typed: at runtime, 'b' has the static type of "BigInteger"

the compiler just inferred the type for you so you don't waste precious keystrokes

oh im using the wrong term. but yeah its bad and dumb and dangerous since the compiler cant warn you if the rhs changes resulting in runtime failures.

its bad bad bad. dont do it. the lhs must remain properly typed.
