Either for comparisons or initialization of a new variable, does it make a difference which one of these you use? I know that BigDecimal.ZERO is a 1.5 feature, so that's a concern, but assuming I'm using 1.5 does it matter? Thanks. ...
I am working on refactoring some old code and have found few structs containing zero length arrays (below). Warnings depressed by pragma, of course, but I've failed to create by "new" structures containing such structures (error 2233). Array 'byData' used as pointer, but why not to use pointer instead? or array of length 1? And of course...
I know you can't rely on equality between double or decimal type values normally, but I'm wondering if 0 is a special case. While I can understand imprecisions between 0.00000000000001 and 0.00000000000002, 0 itself seems pretty hard to mess up since it's just nothing. If you're imprecise on nothing, it's not nothing anymore. But I do...
Hi all, I have a textbox in Javascript. When I enter '0000.00' in the textbox, I want to know how to convert that to only having one leading zero, such as '0.00'. Please anybody help me in this regard. Thanks in advance.. raja. ...
i'm working on a project where i find i'm checking for the following in many, many places: if(item.Rate == 0 || item.Rate == null) { } more as a curiousity than anything, what's the best way to check for both cases? I've added a helper method which is: public static bool nz(object obj) { var parsedInt = 0; var parsed = int.Try...
Duplicate of this one. What would you use to pad zeroes to the left of a number in Flex/AS3? Is there an equivalent to printf or NumberFormat that does this? I'm looking for the nicest implementation of this or something similar: public function zeroPad(number:int, width:int):String { // number = 46, width = 4 would return "0046"...
I watched in horror this morning as a script, running on two different machines, happily loaded, updated, and saved. I'm running ruby 1.8.6, AR 2.2.2. I started playing with some test cases and found reduced it to a minimal reproduction case: irb(main):059:0> first = Job.find :first => #<Job id: 323, lock: 8, worker_host: "second"> i...
EDIT: Apparently, the problem is in the read function: I checked the data in a hex editer 02 00 00 00 01 00 00 00 00 00 00 00 So the zero is being stored as zero, just not read as zero. Because when I use my normal store-in-bin file function: int a = 0; file.write(reinterpret_cast<char*>(&a), sizeof(a)); It stores 0 as the char ve...
The MSDN documentation mentions that double type includes negative zero. However, both -1.0 / double.PositiveInfinity and -double.Epsilon / 2 appear to return normal 0 (and compare equal to it). How can I get -0? ...
Hi All I have two tables, one with all my Branches, and one with all my sales. The sales table also contains a Sales Rep ID, a Branch ID, a month and a year. I need a query that will return the sum of a specific rep's sales for a year, grouped by branch and month, and the query must return 0 if there has been no sales in a branch for ...
We're using SQL Server Standard Edition 8.00.760 (SP3) on a Small Business Server 2003 platform. While tracking down an inexplainable System.Data.DBConcurrencyException for a Strongly Typed DataSet, I discovered the following problem: Given is this table: CREATE TABLE [dbo].[Auszahlung]( [auszahlungid] [int] IDENTITY(1,1) NOT NULL,...
Is there a precondition to calling GetDeviceCaps? I'm trying to discover (at run-time) whether the native screen resolution for a Windows Mobile device is QGVA or VGA. The following return values are all zero in OnInitDialog(): CDC* dc = GetDC(); int horzRes = GetDeviceCaps( HDC(dc), HORZRES ); int vertRes = GetDeviceCaps( HDC(dc), VE...
Alice & Bob are both secret quadruple agents who could be working for the US, Russia or China. They want to come up with a scheme that would: a) if they are both working for the same side, prove this to each other so they can talk freely. b) if they are working for different sides, not expose any additional information about which side...
I want to pad some percentage values so that there are always 3 units before the decimal place. With ints I could use '%03d' - is there an equivalent for floats? '%.3f' works for after the decimal place but '%03f' does nothing. ...
Hay, how would i go about 'zero filling' an integer? ie 1 becomes 0001 40 becomes 0040 174 becomes 0174 Thanks ...
