Between 2019-08-05 00:00:00Z and 2019-08-06 00:00:00Z

I have a variable representing money and it is a sqlite3_uint64 and the compiler yells at me when i compare it against signed integers which makes sense.. but I am not sure how to fix it.

u should tell what it yells

I was thinking about converting the normal integers to unsigned as well by creating a new variable for the comparison.

08:40

The compiler says comparision between signed and unsigned int

hm

08:41

u should decide to cast one

08:41

either the signed or the unsigned

08:41

i guess

yea

08:42

but how to cast xd

08:42

in the ifstatment?

r u in c

08:42

or c++

c++

08:42

tw

well

08:42

i guess u hate modern

08:42

so

xd

(int)

ya thought so

in modern i think it would be static_cast<int>()

08:43

xd

but can that casting mess something up

well yes

i mean it is money

u should then just store money in signed

so i shouldnt fuck that up or fokko exploits the shit of mi server

if it gives u so much trouble

08:43

not like u will have max int money

08:43

or just use a long

but longs are so small

no they arent

how to fit in the money of rich ppl

+9,223,372,036,854,775,807

08:44

its not small

thats a long?

ye

that looks kinda good

https://en.wikibooks.org/wiki/C_Programming/limits.h

i thought when i looked the last time it showed a smaller number

08:45

but the thing is i thought ill be saver with unsigned since nobody should ever have negative money

if u handle ur logic correctly

08:46

then no one will have negative

08:46

and in real world is possible to have negative money btw

08:46

when u owe shit

meh i thing i switch back to long

08:46

wait or isnt the long long? or int64

08:46

wasnt that bigger

08:47

or less supportet? idk

long and long int are identical. So are long long and long long int. In both cases, the int is optional. As to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long.

I am transitioning from Java to C++ and have some questions about the long data type. In Java, to hold an integer greater than 232, you would simply write long x;. However, in C++, it seems that lo...

08:48

long is a int64

08:49

Long and long int are at least 32 bits. long long and long long int are at least 64 bits.

08:49

but if ur compiler is 64bit long will probs be 64bit

i guess ill use int64 then xd

08:49

how it was before

?

08:49

it has been always like this

i mean that datatype i used before

08:50

was int64 so ill go back to that

08:50

i replaced it with sqlite3_uint64 at some point uz i thought i was smart

08:50

@Ryozuki long is 32 bit on 32 bit systems and on 64 bit windows

12:09

use explicitly sized types instead (int64_t)

ye thats what i said

woops

Long and long int are at least 32 bits. long long and long long int are at least 64 bits.

12:10

right?

in practice, that's right I think

12:12

uh, apparently it's even guaranteed by the standard

12:12

but just specify the bit width explicitly

12:18

Note: as with all type specifiers, any order is permitted: unsigned long long int and long int unsigned long name the same type.

C11 adds long long int, it is guaranteed to fit 64bits
