Hello: I want to know how to set the number of digits in the fluent console.
The defaults are only 6 digits in the output screen, the "XYZ" residual and all the monitor value, and the report values. I have used the double-precision fluent, but it still can't output more digits.
Could you please give me some suggestions?
Regards
You need to submit a MWE first, for anyone to find an error/correction in it.

We are working with Amounts of which value are higher. We are displaying the formatted amount in the respective spark TextInput. We are using the simple mx CurrencyFormatter for formatting the amount values. We dont have any problems till 16 digits . But after crossing 16 digits , the numbers are automtically rounded off. We are using the CurrencyFormatter with the following configurations,
<mx:CurrencyFormatter id="formateer" thousandsSeparatorTo="," decimalSeparatorTo="."
precision="2" currencySymbol="" rounding="none" />
My output:
We dont have any problem upto 16 digits
original-->1234567890123456
Number(txtInput.text)-->1234567890123456
formatted-->1,234,567,890,123,456.00
Erroneous output:
original-->12345678901234567
Number(txtInput.text)-->12345678901234568
formatted-->12,345,678,901,234,568.00
Here the last digit 7 is rounded to 8.
Erroneous output:
original-->12345678901234567890
Number(txtInput.text)-->12345678901234567000
formatted-->12,345,678,901,234,567,000.00
I have debugged the code and had gone into the format() method CurrencyFormatter . There actually the problem occurs from the Number conversion. I am wondering since the Number.MAX_VALUE is 1.79769313486231e+308 .
Also I found one more weird behavior of the Number. I described below,
var a:Number = 2.03;
var b:Number = 0.03
var c:Number = a- b;
trace("c --> "+c);
Output : c --> 1.9999999999999998
This kind of output is obtaining for this numbers only.
Please suggest me how to solve this issue or suggest me a workaround method.
Thanks in advance.

It's a common problem with big numbers in languages that use 64-bit floating point arithmetic (Actionscript and Javascript are the same in this, to make an example).
It has nothing to do with the CurrencyFormatter, if you try to trace(12345678901234566+1) you'll get 12345678901234568. That's because that number has so many digits that fills the 64-bit storage space and so it gets rounded off. I realise the explanation is quite simplistic, the argument is in fact quite complex.
There are a few BigInt libraries already available (i think as3crypt has one) that can be used if you have to do some arithmetic ... for the formatting i think you'll have to roll your own
EDIT:
out of curiosity, you can use this to see how your number is being represented in the IEEE754 binary format
Does anybody know which symbol is used by jscript's Number constructor to separate decimal places? Is it always a dot or dependent on locale?
I´m trying to create a number as follows:
Number(2,11):
But the result is NaN
I would bet that the symbol is always a dot but I would like someone to confirm that. Is there a way to indicate which symbol should be used for decimal places?
Thank you.
It's always a dot, though there are a number of other legal syntaxes

I have a graph that displays the count of files in a directory. I need the exact number of files in the graph but I cannot find that feature in the Zabbix configuration.
Any suggestions?
I've just found answer.
We need to change ZBX_UNITS_ROUNDOFF_UPPER_LIMIT in /include/defines.inc.php - It is responsible for number of digits after comma, when value is greater than roundoff threshold. By default it is 2.
why is this so?
when i try out:
Math.pow(2,58)=288230376151711740
while in fact, it is 288230376151711744
or
Math.pow(2,57)=144115188075855870
while it really equals 144115188075855872
it just throws that number without any warning.
i would understand if it stopped going above some number in case of maximum value reached. however, this seems to calculate the first n digits correctly and then go wrong at the very end of the digits only
You've ran out of Number type display precision. The trick is that with powers of 2 the actual value stored in the variable will be precise, while when you'll trace it the engine will truncate the displayed value by 16 digits, as it divides by 10 in process, and leftovers will eventually hit "machine zero" if compared to original value taken without exponential part. This is made to prevent white noise generated by imprecise floating-point division to be displayed. You can work around this issue if you'll advance to big integers/floating point numbers, that store more bits than a double precision number.
I have a SSRS report with full of number fields. I would like to have that to be displayed as in one decimal. i tried to use F1. it gives me only one decimal points in html rendering, but in excel exported version it shows 2 decimal points.
How can i have just one decimal point both ecxel and html rendering.
Please comment.
Thanks in advance

Use N1 as your Format Property setting. N denotes Numeric formatting, the 1 denotes the number of decimal places, so N2 would give you 102.02, for example. This should carry to excel as it is rendered in html.
Alternatively, you could use the format code #,##0.00, which will give you the thousands separator and two decimal places. '#' indicates optional characters, whilst '0' indicates mandatory characters (nulls will be replaced by '0.00').
in 2012 version: FormatNumber(Fields!col.Value,2)
Right click on the text box that contains the value you would like manipulate, select TEXT BOX PROPERTIES. Navigate to the Number tab, select Number and the # of Decimal places you want the box to allow for.
