to 4 decimal points

[twistedpancreas]

Ok i'm lost, even though I've asked this before.

I've got my file here http://home.exetel.com.au/twistedpancreas/images/test1.fla , calculating an equation.

But once again I need the answer to be to 4 decimal points (ie like an answer of 0.0393), but for the life of me I can't get it to work.

I tried *100 / 100 but i'm just confusing myself.

Sorry for my lack of knowledge, but i appreciate the help.

post a link to your fla.

[twistedpancreas]

yeah sorry i was going to do that but our network here was mucking up

ok here it is http://home.exetel.com.au/twistedpancreas/images/test7.fla

[twistedpancreas]

actually i've updated my file to resemble how the setup will work

see http://home.exetel.com.au/twistedpancreas/images/test8.fla

i now have input3 as iodine and it's now giving me an answer but i think it's stuck on trying to round the number down to 3 significant figures (ie 0.0210), thus the answer will always be incorrect at the moment

any help would be most appreciated

thanks kglad that's the ticket!

it's all now making a little more sense, although i've still got to get my head around some of the code (but big thanks to all who helped out)

my latest file is now http://home.exetel.com.au/twistedpancreas/images/test9.fla

got one small additional question (and maybe it should be a new topic), but is there anyway for the first check button to check for all numbers within the random range of numbers and return them as the correct answer if typed into titration.text (ie titrationValue = any result within the range of 0.02050 to 0.02080)?

i hope that makes sense

you're welcome.

you are a living legend kglad and you get my favourite person of the day :D

thanks a million!!!

my knowledge is slowly building, and a lot of it is due to this forum, thx all!

[kglad]

you're welcome.

sorry to bring this one up again, but my client is now wanting this code to end up with no decimal point, ie if the answer was 446.5, then they'd want the answer as 447, and i'm a bit frazzled as to what to do, here is my code at the moment...

That is SO much simpler .. just use Math.round

var multiNum:Number = 723699;
this.iodine = (Number(molInput.text)*Number(titrationInput.text))*multiNum;
this.iodine = Math.round(this.iodine);
trace(this.iodine)
this.titrationDisplay.text = this.iodine;

um i'm getting NaN when molInput.text = 0.0391 and titrationInput.text = 0.01630

[twistedpancreas]

isn't iodine being defined twice there?

shouldn't it be something like

[Newsgroup_User]

> isn't iodine being defined twice there?

No its fine

[Newsgroup_User]

> um i'm getting NaN when molInput.text = 0.0391 and titrationInput.text =
> 0.01630

Then there is something going on you're not telling us, as the script will
work with those inputs .. are you sure there.s not other characters in the
strings?

[twistedpancreas]

yeah could be (knowing me)

here's my file: http://home.exetel.com.au/twistedpancreas/roundingNumbersTest.fla

it's got me stumped!

[kglad]

just use Math.round() on your answer.

[Newsgroup_User]

If you look at your trace output, you'll see they have extra newlines at the
end.

That's because you've made the input text boxes multi-line .. they should be
single-line

Pretty obvious really .. once you see it.

ok thanks kglad,

that worked on my original code, but how come it's not working on http://home.exetel.com.au/twistedpancreas/roundingNumbersTest.fla

ie, Jeckyl's code

[kglad]

don't use multiline textfields.

[twistedpancreas]

doh!!!

thanks kglad and jeckyl

why do multiline textfields stuff it up?

[kglad]

you're welcome.

actually, it's your letterspacing being non-zero incombination with the textfield being multiline that causes flash to add a carriage return.

[twistedpancreas]

ah ok, but generally Flash just dislikes multiline textfields?

[kglad]

no, not at all. it just depends upon your needs.

but if you want to input a number, it doesn't make sense to use a mulitline textfield.

[joshspoon1]

I was reading this thread and made a class of your decimal function

class com.joshspoon.utils.Mathtilies
{

public function Mathtilies ()
{


}
public static function decimalPlaces (NumbertoConvert, DecimalPlaces) : Number
{
NumbertoConvert = NumbertoConvert;
DecimalPlaces = DecimalPlaces;
var input3 = Math.pow (10, DecimalPlaces);
var numericVal = Math.round (NumbertoConvert * input3) / input3;
var stringVal = "" + numericVal;
if (numericVal < 1)
{
// length should be 2+DecimalPlaces
while (stringVal.length < 2 + DecimalPlaces)
{
stringVal = stringVal + "0";
}
} else
{
// should have DecimalPlaces digits after the decimal, if there is a decimal
var decimalPos = stringVal.indexOf (".");
if (decimalPos > - 1)
{
// has a decimal
while (stringVal.charAt (decimalPos + DecimalPlaces) == "")
{
stringVal = stringVal + "0";
}
} else
{
// no decimal
stringVal = stringVal + "." + (input3 + "").substring (1);
}
}
return stringVal;
}
}

If any one want it.
