Greetings:
Is there a way of rounding up floating point numbers without CASTing as shown in a number of the replies ? For example, a table value is 103.365 and I'd like to see values of 103.365 and above (103.366,103.367, 103.368, 103.369) rounded to 103.37. Is is possible to do this with a function or setting in SQL Server 2005 or is it necessary to write T-SQL to do the rounding ?
Thanks.

Hello,
I have a problem with the round of SQL Server 2K on the float data type.
In my application I do a SQL request for find a row in a table of SQL Server 2K.
This is the request :
SELECT DISTINCT N_ROW_ID FROM COMM WHERE N_ARTICLE_ID=79510 AND N_DATASOURCE_ID=1 AND N_SOURCE_ID=-102 AND N_PROVIDER_ID=-100
AND N_LEAD_TIME IS NULL AND N_UNIT_PRICE = 329.78 AND N_UNIT_PRICE_CURRENCY_ID=1
N_UNIT_PRICE is a float data type.
In the line need, the field N_UNIT_PRICE has 329.78 but with the round of SQL Server 2K I have 329.779999999999997.
So I never find the row
Do you have a solution for comparate a float flied with SQL Server round and a float send in a request as my 329.78?
I can't transform the column in decimal or numeric data type.
Is it possible to Disable the function?
Regards
I have a float of 70.83333333343
If I do this
SET @Output=ROUND(@Output, 2, 1) -- @Output is DECLARED as FLOAT
I get this:
70.82999999999999
I want:
70.83
How do I do that?
Thanks in advance...
Hi,we found some strange behavior when operating with floats and round().The following simplified statement reproduces the problem.select 6.56 - round(convert(float, 6.56), 2)from sysusers where name = 'public';===========-8.88178419In "real world", the floats are not literals, but float fields in tables.I could figure, that 6.56 - 6.56 will result in something like 0.00001,but -8.88178419 is beyond my imagination.The same statement without round results in 0.Has anyone any clue on this?Regards,Peter
View 5 Replies View Relatedfor MS SQL 2005 I am having
SELECT name.Name
, Percentage = (count(*) / ((SELECT tot = COUNT(*) * 1.0 ) FROM dbo.Name)) * 100)

how can i CAST and ROUND (count(*) / ((SELECT tot = COUNT(*) * 1.0 ) FROM dbo.Name)) * 100) ?
then ROUND (the result, 2) ?
CAST(count(*) / ((SELECT tot = COUNT(*) * 1.0 ) FROM dbo.Name)) * 100) AS DOUBLE does not work
thank you for helping
I can't take full credit for this. I want to share this with Jeff Moden who did the important research for this calculation here.
All I did was just adapting some old code according to the mantissa finding Jeff made and optimized it a little
Some test codeDECLARE@SomeNumber FLOAT,
@BinFloat BINARY(8)
SELECT@SomeNumber = -185.6125,
@BinFloat = CAST(@SomeNumber AS BINARY(8))
SELECT@SomeNumber AS [Original],
CAST(@SomeNumber AS BINARY(8)) AS [Binary],
dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Converted],
@SomeNumber - dbo.fnBinaryFloat2Float(CAST(@SomeNumber AS BINARY(8))) AS [Error]
And here is the code for the function.CREATE FUNCTION dbo.fnBinaryFloat2Float
(
@BinaryFloat BINARY(8)
)
RETURNS FLOAT
AS
BEGIN
DECLARE@Part TINYINT,
@PartValue TINYINT,
@Mask TINYINT,
@Mantissa FLOAT,
@Exponent SMALLINT,
@Bit TINYINT,
@Ln2 FLOAT,
@BigValue BIGINT
SELECT@Part = 1,
@Mantissa = 1,
@Bit = 1,
@Ln2 = LOG(2),
@BigValue = CAST(@BinaryFloat AS BIGINT),
@Exponent = (@BigValue & 0x7ff0000000000000) / EXP(52 * @Ln2)
WHILE @Part <= 8
BEGIN
SELECT@Part = @Part + 1,
@PartValue = CAST(SUBSTRING(@BinaryFloat, @Part, 1) AS TINYINT),
@Mask =CASE WHEN @Part = 2 THEN 8 ELSE 128 END
WHILE @Mask > 0
BEGIN
IF @PartValue & @Mask > 0
SET @Mantissa = @Mantissa + EXP(-@Bit * @Ln2)
SELECT@Bit = @Bit + 1,
@Mask = @Mask / 2
END
END
RETURNSIGN(@BigValue) * @Mantissa * POWER(CAST(2 AS FLOAT), @Exponent - 1023)
END
Thanks again Jeff!

Dear Programmers,

Hi all,
I am sorry if i am posting this error in an inappropriate froum.
Well in my asp.net intranet web application i want to enter a number to the database(sql sever 2005) that has a column(schoolkm) whose type is decimal(9, 2). Now if i want to enter the value 1.5 in the text box and enter that value to the database through interface then that value automatically rounds to 2. But when i get into the table and enter that value by hand then that value enters perfectly i.e. without rounding of. I want to know the reason and how can i cure this problem.
Regards & thanks in advance
I have table with data type decimal (18,2) when i try to load more then 2 decimal it is rounding off

Anybody noticed that SQL Server rounds up if the value is half waybetween two rounded values, but C#'s Decimal.Round(Decimal,Int32)rounds to nearest even number?[color=blue]>From MSDN: "When d is exactly halfway between two rounded values, the[/color]result is the rounded value that has an even digit in the far rightdecimal position. For example, when rounded to two decimals, the value2.345 becomes 2.34 and the value 2.355 becomes 2.36. This process isknown as rounding toward even, or rounding to nearest."I perform the same calculation sometimes on the web server in C# andsometimes at the database in T-SQL, but want to get the same resultfrom both calculations. Could anybody offer any strategies for dealingwith this?Thanks ~ Matt
View 3 Replies View Related1. In c++ (or any other language) I'm copying bit by bit to a doublevariable dob_var.2. If I copy dob_var to dob_var2 which is also a double I do not loseinformation.3. This implies that the same would be when copying to a data base, butwhen I write dob_var to an sql server float field (same size as adouble variable = 64 bit) it sometimes loses information. e.g. whenvalue=1E-320.It is true that SQL float is valid until 1E-308 but so is a C++ double.Any comments?

Hi all,
I am developing an application for a big office which uses SQL Server 2000.
Apart from my database, on that server, there are two databases by other companies.
The administrator also has access to server but the client only wants him to backup the database.
I have two questions:
1) First of all (if it is possible) I would like to protect my own database from the other companies.
I don't want them to:
see the data in the tables (around 20 tables)
make changes to the stored procedures (more than 100 stored procedures)
be able to backup the database
2) The client will save sensitive data to the database (mainly currency amounts, salaries etc) which he wants to keep hidden.
I am using float type for these fields and I would like to make the data encrypted. I could do it for nvarchar fields but changing these float to nvarchar would be time consuming.
Thanks for your patience reading this!
Would really appreciate some help on any of these

View 3 Replies View RelatedHas anyone been experiencing problems with rounding to 2 decimal places in SQL 7? I have a bunch of queries that generate web reports. Under 6.5 everything was fine. Now under 7.0 any number that needs to be rounded to 2 decimals is actually giving me several decimal places.
Here is a simplified version of what I am doing:
DECLARE @x real
DECLARE @y real
SELECT @x = 223.1
SELECT @y = 59.7
SELECT ROUND((@x/@y),2)
Result should be 3.74. But instead I am getting 3.7400000000000002
If anybody has heard if Microsoft has declared this as a known bug please let me know.
Thanks for your time.

There is a filed in a table of type decimal(12, 8)
when running a select query on this table for this field i.e.
select field1 from table1
the data is shown like:
102.12500000
104.12500000
And therefore the report shows the same figure.
How do I get this field to show up in the report as 4 decimal places. i.e.
102.1250
104.1250
Tried the properties of the cell to format the text into a number but there is only 2 decimal places there.
Even tried the expression by using Rnd(field1). This does not seem to do what I am after.
Thanks
How do I write sql syntax to round the last digit. For example, 12.152 should be 12.15. My current sql syntax does not round the last digit as follows:
Select tblARInvoiceDetail.UnitPrice * tblARInvoiceDetail.Quantity AS ChargeBeforeDiscount
FROM tblARInvoices INNER JOIN
tblARInvoiceDetail ON
tblARInvoices.ARInvoiceID = tblARInvoiceDetail.ARInvoiceID
The tblARInvoiceDetail.UnitPrice column is numeric;length 9;precision 18
The Quantity column is integer;length 4; precision 10;scale 0
Any Suggestions?
Thanks,
