toDouble()k
karelpeeters
11/10/2018, 7:41 PMOkay but that's for both of my above cases, do you want both to go to doubles?
h
Hullaballoonatic
11/10/2018, 7:41 PMautomatically, yeah
k
karelpeeters
11/10/2018, 7:42 PMThe first one I understand, I agree that it's annoying without any real safety benefits.
h
Hullaballoonatic
11/10/2018, 7:42 PMalso, is double just a float with twice the memory allocated?
k
karelpeeters
11/10/2018, 7:42 PMBut
3 / 2h
Hullaballoonatic
11/10/2018, 7:42 PMi know i learned that at one point, but forgot it, because i learned it before it was of any practical use to me
k
karelpeeters
11/10/2018, 7:42 PM(Yes, double is float with more bits)
h
Hullaballoonatic
11/10/2018, 7:43 PMmeaning you want
3/2k
karelpeeters
11/10/2018, 7:43 PMYes, I use that a lot.
h
Hullaballoonatic
11/10/2018, 7:43 PMah, good point
Hullaballoonatic
11/10/2018, 7:44 PMi guess i never considered it because in java you have to use ceiling and cast back to int
Hullaballoonatic
11/10/2018, 7:44 PMor i think casting back to int does that by itself now that i think about it..
k
karelpeeters
11/10/2018, 7:44 PMNo, it's the same in Java and every other C-like language there is.
karelpeeters
11/10/2018, 7:44 PMNot even a cast, that's literally what / on its does.
h
Hullaballoonatic
11/10/2018, 7:44 PMnvm me then... i'm dumb!
k
karelpeeters
11/10/2018, 7:44 PMThat's also what the dedicated CPU instruction does :)
h
Hullaballoonatic
11/10/2018, 7:45 PMi just like my math equations in my code to be devoid of much other than variables, numbers, and mathematical operators
Hullaballoonatic
11/10/2018, 7:45 PMthe casting distracts the eye from the important parts
c
Chris Cunningham
11/10/2018, 7:45 PMJust write it with the decimal point 3.0 / 2.0
Chris Cunningham
11/10/2018, 7:46 PMOtherwise it would think you are working with int and not double
h
Hullaballoonatic
11/10/2018, 7:46 PMmaybe the same reason i don't like
!foo.isEmptyfoo.isNotEmptyHullaballoonatic
11/10/2018, 7:46 PMyeah, you're very correct, Chris
Hullaballoonatic
11/10/2018, 7:47 PMbut that doesn't work if your integers are stored as variables
c
Chris Cunningham
11/10/2018, 7:48 PMOh so you mean wanting to divide ints with a double result
h
Hullaballoonatic
11/10/2018, 7:48 PM Copy code
val foo = 3
val bar = .3
println(foo + bar)c
Chris Cunningham
11/10/2018, 7:48 PMYeah need to cast one of them
h
Hullaballoonatic
11/10/2018, 7:48 PMi've been dissuaded from dividing ints into automatic doubles
c
Chris Cunningham
11/10/2018, 7:48 PMI still rather cast, type conversion should be explict
h
Hullaballoonatic
11/10/2018, 7:49 PMmaybe i just like java's casting more than kotlin's?
c
Chris Cunningham
11/10/2018, 7:49 PMTalking as vs a cstyle cast
h
Hullaballoonatic
11/10/2018, 7:49 PM(int)toInt()Hullaballoonatic
11/10/2018, 7:50 PMor
as IntHullaballoonatic
11/10/2018, 7:50 PMbut i get it
Hullaballoonatic
11/10/2018, 7:50 PMthere's no perfect solution here, and i appreciate hearing the counter-arguments
c
Chris Cunningham
11/10/2018, 8:54 PMYeah I am pretty used to the c style ones
Chris Cunningham
11/10/2018, 8:55 PMNot sure about kotlin but in C#
(T)as Tk
karelpeeters
11/10/2018, 10:22 PMBtw if you're really frustrated about this you can define/generate code like
inline operator fun Double.plus(other: Int) = this + other.toDouble()h
Hullaballoonatic
11/10/2018, 10:22 PMokay, thanks, Karel! you're so helpful
c
Chris Cunningham
11/10/2018, 10:37 PMjust be sure that is known and does not confuse the crap out of the rest of the devs on the project
