Is there a way where I can get the #.# not to return as rounding to the nearest tenths place?
Example: For FY15 I need 4.0 to return but right now the only way I see that 4.0 is when I add the hundredths place 4.08.
Don't want: 4.08
Want: 4.0
Is there a way to accomplish this?
If I palce the number with 2 decmials, the #.## is correct. Example below.
However, when i place the number with 1 decimal, the number rounds up to the nearest tenths place. I don't want that. Example below.
Try using a floor function on your values.
Example: 4.08
First, to preserve the first decimal place, multiply by 10.0. This gives 40.8.
Now use the floor function on 40.8, which gives 40.0.
Finally, divide by 10.0 to return to the degree of the original number, giving 4.0.

I need the square root of a float, in CUDA device code. Hard to say whether speed matters more than accuracy in my use case.
__sqrtf CUDA intrinsic is the natural choice
But then I saw the various __fsqrt with rounding CUDA intrinsics;
What is rounded in these intrinsics; the argument "x" or the return value? Or do I misunderstand the meaning of rounding here?
My testing suggests neither is rounded! I wrote a kernel that evaluates:
__fsqrt_rn(42 * 42 + 0.1)
and the return value is always 42.0011902, which is equal to the square root of 42 * 42 + 0.1. So what is being rounded?
It's a rounding mode for the result. Input arguments are not "rounded" before they are injected into the arithmetic flow.
the "rn" rounding "direction" is "round-to-nearest"
It means that at whatever precision the interim result is being calculated to, that result will be rounded to the nearest available representation. In the case of a float final result, it will be rounded to the nearest available float representation.
Let's revisit your example. When I put your problem into the windows 10 calculator, the result I get is 42.001190459319126303634970957554 The way we get from that "correct result at arbitrary precision" to a 32-bit floating point "rn" result is to take the two 32-bit floating point numbers, one which is closest but numerically higher, and one which is closest but numerically lower, and of those 2, select the one that is closest. That is apparently 42.0011902.
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
In my report I'm trying to remove the decimals without rounding. I'll be using this to set the minimum value in the vertical axis of the area chart.
So I tried =Format(98.56, "N0"), but this returns 99, which is incorrect. It should return 98.
I've been searching specifically for SSRS, but most of the results are for tsql.
My question: How can I remov decimals in SSRS without rounding?
Thanks
Try using "Floor". It effective rounds down to the nearest integer. You'll find this under the Math functions.
=Floor(Fields!Number.Value)
Note, there's also a Floor function in Transact-SQL that works the same way in case you need to do some of the processing in your SQL script.
Update based on request in comments
If you wanted to achieve the same result after the decimal point, all you need is a little algebra.
=Floor((Fields!Number.Value*10))/10
That should turn 99.46 into 99.4. Given that it shaves off the remainder, you could then tack on any additional zeroes you wanted.
I ended up converting to Int. The following expression in SSRS returns 98:
=Int(98.56)
I know the question is quite old, but as I ended up here having the same question I would like to share my answer:
While FLOOR and CEILING are fine if you take extra measures to handle numbers <0 or know they are always >=0, the easiest way to simply strip off the decimals is to use
=Fix(Fields!Number.Value)
FIX only returns the integer part of a number, without any rounding or transformation. For negative numbers Int rounds up.
Source: Examples for Fix, Floor and Ceiling
Source: Difference between Int and Fix
For example, if I am given a value 3.5, I wish to round it up to 4.
If I am given a value 3.4, it will be rounded down to 3.
I've tried the ceil and floor function. However, they are both only able to round up and down respectively.
This are what I've tried.
SELECT floor(avg(rate)) as average_age FROM review
gives 3 while
SELECT ceil(avg(rate)) as average_age FROM review
gives 4.
Well the answer is ROUND() as given by eggyal.
On a report I have the following code for a field:
=Sum([PartQty]*[ModuleQty])
Example results are 2.1 and 2.6. What I need is for these value to round up to the value of 3. How can I change my field code to always round up the results of my current expression?
This is an old Access trick I learned a very long time ago, and it makes use of the way Access handles fractional, negative numbers. Try this:
-Int(-[DecimalValue])
It's odd, but it will always round your numbers up to the nearest whole number.
you could do
=Int(Sum([PartQty]*[ModuleQty]))+1
I think. That would get the Int part of the sum (2) and then add 1. you might need to be a little more clever as this will probably give you 3 even if the sum is exactly 2, which is probably not what you want.
not tested it but something along these lines might work (access syntax is not that great, but should give you the right idea) :
Iif(Sum([PartQty]*[ModuleQty])-Int(Sum([PartQty]*[ModuleQty]))=0,
Sum([PartQty]*[ModuleQty]),
Int(Sum([PartQty]*[ModuleQty]))+1)
Test this:
Round(yournumber + 0.5, 0)
