How can I always take the leading zero from my number? I tried many things but still i was not able to take out the leading zeros. Replace function wonot do the trick! coz it will take all zeros out.
Example:
00672656 ---> should be 672656
02074310 ---> Should be 2074310
=CInt(Fields.YourColumn.Value)

I was wondering how to construct a Turing Machine for
A<B<C<D...<N
with all numbers (A,B,C,D,...,N) being positive binary numbers.
These are a couple examples of how the machine should work:
1001 - Accepts because there is only one number
0<1 - Accepts
0010<1000<0001 - Doesn't accept because 1000!<0001
0100<1010<1010<1000 - Doesn't accept because 1010!<1010
I've tried methods that work to compare only two numbers but I can't seem to find a way to compare multiple (should work for infinite number of inputs) numbers.
Here is a high-level block diagram for solving this problem. You can implement these blocks by using block feature of JFLAP.
Blocks Description
Done? : This block decides whether all comparisons are done, if yes, it accepts, otherwise, it goes to compare the very next two numbers.
A<B : This block is responsible to compare two binary numbers, the one that cursor is pointing at the first digit and the next one. You can use '<' as the separator between A and B and the next number.
cleanup: during the comparison, you might marked 0's and 1's to something else. This block clean up everything and prepare everything for the next comparison.
Hopefully, this gives you an idea to solve the problem.
I'm trying to get the average number, and then remove the trailing, pointless zeros afterwards, (new to SQL) but I can't understand why it wont remove them, do I have the wrong idea??
So far I have;
SELECT total,
AVG(total(TRUNCATE(total/1,2))
I think you are looking for cast as below.
select cast(17.800000 as dec(3,1))
Result:
val
----
17.8
so you query will be
SELECT total, cast(AVG(total) as dec(3,1))
considering you just need 2 digit before . If you need more digits, you can adjust it accordingly.
DEMO
Assuming you are using SQL Server then you can cast the answer to a decimal with one decimal point:
select cast(avg(total) as decimal(9,1))
This SQLFiddle shows it: link
SELECT
TRUNCATE(AVG(myFloat), 2),
AVG(myFloat),
ROUND(AVG(myFloat), 2)
FROM docs
You should probably use ROUND instead of TRUNCATE.
The stuff after the decimal is odd because of floating point math, and there are occasions where floating point math is internally calculated as .009999999 instead of .01000000000
I believe these answers that use a CAST may have the same truncation problem.
You simply want to avoid casting or truncation when you are removing the decimal places beyond what you're interested in. Be explicit in what you are doing and less mistakes will pop up later.
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
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.
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)
