<1> :D
<1> hi all
<2> hi preach
<1> :)
<3> hi
<1> hi calchas
<1> qaj have a major problem :'(
<1> swing staff problems
<4> Sounds more like trollish problems. Thats the kind of staff I'd expect gnomes and trolls to carry.
<1> exactly tollish mc flurry broblems :'(
<1> trolish*
<2> :/
<1> let me type it correctly cause im excited
<2> lol @ excited
<1> exactly trollish mc flurry problems :'(
<3> Lion-O please calm down a bit an give people a chance
<1> tel him calchas
<1> cause he is rude with me
<1> :'(
<3> Preach21m, what is your actual problem
<4> calchas: Oh I am calm. If I wouldn't he wouldn't be here anymore.
<1> my problem is that i dont have an actual problem :/
<3> Preach21m and you should keep out of it and not inflame
<3> cool, tem be sensible
<1> Lion thank you i appreciate lets start a new year
<4> calchas: besides; I think you forgot the last year where he was spamming the channel with that annoying crap for half a day. I have my reasons here.
<1> now we are okay?
<1> a new year?
<1> i just came here 1 time
<1> when i had a problem
<1> now i have a problem and i am here again
<3> Preach21m, quiten down unless you have something sensible to say, else you will anger regulars and disrupt the channel, is that a sensible request to you ?
<1> disrupt who?
<1> its so quit here
<1> however
<1> i have a problem
<1> i think you noticed that!
<1> :D
<3> state it of be removed
<1> removed what?
<3> from the channel
<1> wb mr
<1> i said welcome back mister
<1> 0_o
<1> not even a thank you?
<3> do you have a real java problem?
<1> yes i do have a real java problem
<3> what is it
<1> java problem i just said it :/
<3> hi Rob_uknow
<5> calchas
<5> hi
<6> hi, i just figured out i made a terrible mistake .. im using doubles and found out a problem with precision
<5> you did?
<6> pretty stupid of me :/
<6> yes heh
<6> only after googling i discovered the problem
<3> what sort of app is this
<3> doubles have a fairly high resolution
<6> numerical
<6> well i have a division
<6> and im comparing to other doubles
<6> but now i noticed that for example i get 5.0000000000000005
<6> so when i compare to 5
<6> obviously i dont get what i want :/
<6> of course now i discovered BigDecimal
<3> strange thing to do anyway
<6> why ?
<6> i mean i have e.g. two vars
<3> as long as you can afford BigDecimal
<6> the problem is converting to BigDecimal :/
<3> equality testing of true reals is usually an issue (uncountably infinite sets and all that)
<6> this is >= and <=
<3> what are you trying to do with the comparison
<6> im comparing the two values, e.g. if they're less then i do something .. etc
<3> maybe do a subtraction and test for a difference less that some small number (the binary quantisation for example)
<6> hmm
<3> >= and <= should pose little to no problem
<3> == is in general a problem
<6> but if one var is 5.0000000005 and the other is 5.0
<6> then it is a problem :/
<3> why
<3> <= will yield a result
<6> if ((x >= x3) && (x <= x4))
<6> in this particular case
<6> x3 and x4 are both 5.0
<3> thats just a replacement for ==
<6> while x is 5.00000000005
<6> yeah, when both x3 and x4 are both the same
<3> so what real problem are you trying to solve
<6> hmm yeah that's the problem
<7> Hello
<6> i have a lot of functions, which im quantising
<6> and then use them to control my light sensor
<6> eventually
<6> i think i'll end up switching to bigdec :/
<3> it's pretty expensive to use
<7> Could anyoen please help me
<7> I have this problem
<3> Pichi ask and see
<5> why use BigDecimal?
<7> When i push a button i the button that i just pussed to take a certain caption
<7> I want sorry
<7> SetText thrown errors
<6> Rob_uknow: to get rid of that annoying problem? (i'm ending up with 5.00000000005 instead of 5, after some calculations)
<6> i only realised about the floating point arithmetic after coding it with double
<5> why not do what calchas said? subtract, if difference bigger then x then its not equal
<3> Pichi at runtime or compile time
<5> or convert to int if you don't need that much precision when comparing
<6> int is not good for me
<6> so i subtract from a treshold value?
<6> sorry subtract, and compare to a treshold ?
<7> At runtime
<7> When i press the button i get errors
<5> what errors Pichi?
<3> on the rare occasions I've needed that (always due to db behaviour never java) I use 100000th of the largest in absolut magnitude of the 2 operators
<3> Pichi which exception
<7> Hold on
<5> take your time
<7> I can't cut it
<5> then copy it instead
<7> :)
<7> Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

<7> It make no sence
<3> is the object you are calling setText on null ?
<3> check with a System.out.println statement before the call
<7> Button sus_st = new Button(" ");
<7> sus_st.setBounds(0,0,70,70);
<7> add(sus_st);
<7> And
<3> don't paste code
<3> check with a System.out.println statement before the call
<7> When i'm presing this button i want it's label to be set to "X"
<3> see my previous comment
<7> Thank you
<8> hey guys need serious help can anybody help me
<4> Undefined: not unless you ask a question.
<5> the question is Undefined
