Float Vs. Decimal
Jun 29, 1998We are having problems with rounding errors on large monetary calculations in sql server 6.5
The calculations include float fields (for volumes and unit of measure conversions in product movements). I was wondering if the float being "approximate" could be the problem.
IF it is, why would I want to store things as a float instead of a dec(28,14)?
Is it faster to compute numbers stored as approximate binaries? Will we see a big performance hit if we switch some of the table`s field`s to decimals?
Thanks in advance.

What DataType Is Best ... Float, Double Or Decimal?
Sep 25, 2006
I am using sql express 2005 and sql server 2005 with C# 2.0.
I am a bit confused about which data type i should be using for several fields.
Right now I am declaring all of my fields in sql server as float for everything except for money fields which are using money.
When loaded into C# these fields are converted to double and decimal because C# does not have a float datatype.
Should I be using Decimal or Double for everything instead?
Here are a few examples
QtyInvoiced (float) - holds the number of items invoice
possible values look like this 1.0, 1.25 or 1.5
PercentDiscount (float) - holds a percentage
possible values look like this
10.25, 20.50, 50.00
I appreciate the help.
Convert Float To Decimal Errors
May 18, 2006I'm trying to move records from a SQL table with a float column to a DB2 database that has the column defined as Decimal (8,2) It keeps crashing saying it has a type mismatch problem. I tried changing my source command to pass in the column already converted and it still crashes on this. I also tried doing a data conversion task to do the conversion and I still get the same error. Any ideas?

Function Required To Convert Packed Decimal In Binary(6) To Int (or Float)
Mar 8, 2007I have been given some data from a Mainframe (AS400?) which has some fields coded in Packed Decimal. I have been able to load the data into a SQL2005 database table, but I now need to convert the Packed Decimal data in the binary(6) field to the appropriate integer (or float) value.
The field contains values such as the following:-
0x20202020200C
0x202020022025
0x20202020DFFA
I don't know how to interpret these. Has anyone got a function that can do this for me?
I've read several articles online that explain how packed decimal works, but none tell me how to interpret the last of my three examples. Can you help?
Thanks!

Mar 28, 2008Happy Friday!
A while since I have posted a question, and this one is probably real easy.
I am trying to store numeric values from a php form in MSSQL 2000 database. However, the columns are set to float and if the value is 1.00, when entered into the table it is saved as 1
If I change the column type to money, the query fails, with an error message of conversion of datatype varchar to datatype money statement terminated.
anybody know what I need to do? do I need to do something in my query to specify that this is NOT varchar data?
Convert A Binary Float To FLOAT Datatype
Apr 9, 2007I 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],

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),

WHILE @Mask > 0

Legacy Database Uses Decimal Data Types.--&> AutomobileTypeId (PK, Decimal(10,0), Not Null) Why Not Integers Instead ?
Sep 26, 2007I am working with a legacy SQL server database from SQL Server 2000. I noticed that in some places that they use decimal data types, that I would normally think they should be using integer data types. Why is this does anyone know?

Data Type With Decimal Point For Decimal Values But Not For Whole Integers
Dec 8, 2013I am creating a table on SQL Server. One of the columns in this new table contains whole integer as wells as decimal values (i.e. 4500 0.9876). I currently have this column defined as Decimal(12,4). This adds 4 digits after the decimal point to the whole integers. Is there a data type that will have the decimal point only for decimal values and no decimal point for the whole integers?

Jul 24, 2006Hello!
I would like to cast (convert) data type decimal(24,4) to

CAST(@variable as decimal(21,4)) or CONVERT(decimal(21,4),@variable)
because of the following error: "Arithmetic overflow error converting

How Can I Use The Decimal Comma Instead Of Decimal Point For Numbers In Jet Engine?
Sep 19, 2007
I wanted to convert a dataset from vb.net (2.0) to an .XLS file, by MS Jet. My national standard is using decimal commas, not decimal points for numbers signing the beginning of decimal places.
But the MS Jet Engine uses decimal point,in default. Therefore, in the Excel file only string formatted cells can welcome this data, not number formatted.
How can I solve or get around this problem? (with jet if it possible)

Decimal Limited To 4 Digits To Right Of Decimal?
Jun 18, 2007
I need to store decimal values: decimal(20,15) in my SQL Server 2005 database.
I load data from flat file, convert it using Data Conversion Task to decimal(with scale: 15) and try to save it using OLE DB Destination.
It works fine for 4 digits after the decimal (like 1.1234), but always failes for more than 4 digits (1.12345).
Is the decimal limited to scale 4 ???
Thank you for your help!

I am having a file in which amount fields are given in a Packed Decimal format. Can anyone suggest me how I can read this data element from the file and convert it into SQL decimal datatype.

Float Precision
Sep 5, 2002Hello everyone,
I am sure this is a newbie question as I am new to Microsoft SQL server but any help is greatly appreciated. I am populating a SQL database from an AS400. The decimal numbers from the AS400 are coming accross with extra decimals. (ie. 63.02 is coming accross as 63.0200001)
Is there a way to limit the number of decimals in a float or real field - or a SQL command I can put in a script to truncate each field to 2 decimal places after they are populated.
Thanks,
Randy
Convert Int To Float

why does converting integer to float take so long? Its a column with about 5 Million rows.
I want to avoid cast(inumber1 as float) / cast(inmuber2 as float), thats why converting them. Queries should be a bit faster after that.. hope so :)
Thanks a lot
Can Anyone Help With With Datatype Float
Aug 30, 2007I have some engineering data in my table and the db designer is representing it with a float datatype. Here's what is happening. If I query on a record based on id num and get a row and put it in text boxes in my Windows App, min_riv_hd_dia (the float) is 0.026<14 zeroes>2. If I try to query and get that same record again but this time based on id num and min_riv_hd_dia equal to 0.026<14 zeroes>2, I get no row found. If I just do a select on this row based on id number, sql server displays it as 0.026. But if I query with 0.026 as my value, still the row is not found. If I query min_riv_hd_dia > 0.026, the record is found.
So my question is, how can I tell the exact value that must be input in my search criteria in order to find this row?
Thank you so much if you can help!
Float In VB-Skript
Dec 29, 2003Hi there
I have two Databases
in both databases are fields with float - no null
If I am transfering data from one database to the other everything works well unless there is a comma in the field ( 0,99 or 123,456 )
"SQLAString = "Insert into InventurDaten (Artikelnummer,Hauptartikelnummer,Auspraegung,Arti kelbezeichnung,Artikeltext1,EDVEingang ,EDVAusgang,InventurmengeEDV) values ('" & ArtNr & "','" & ArtNrT & "','" & AP & "','" & ArtBez & "','" & ArtText & "'," & EDVEingang & "," & EDVAusgang & "," & ArtMenge & ")"
"
where EDVEingang and EDVAusgang are defined as float, no null
Then the programm stops with the following message:
Within the INSERT-Procedure there are less columns then there are Contents in the Value-Clause.
I have to finish the programm until tomorrow morning and don't know what the problem is.
If anybody has an idea, please let me know.
