Here’s another example, this time using N1 to specify that we only want one decimal place: CREATE TABLE #tmp(colA DECIMAL(20,3), colB FLOAT);-- succeeds Converting float and real data. This particular format specifier (N) results in the output being formatted with integral and decimal digits, group separators, and a decimal separator with optional negative sign. The SQL Server treats the 2 numeric (in general sense, not as data-type) 178.7 and 178.70 as exactly the same value and hence it will display 178.7 in the Datasheet. I'm working with SQL server and the float values are not able to be saved. That closest value is -2702489.85637499997392296791077. Follow RSS feed Like. I would suggest casting to decimal instead, as float is an imprecise datatype and is prone to "errors" in the result. For more information, see STR (Transact-SQL) and Functions (Transact-SQL). select CAST(@num AS numeric(10,2)) But this is not the solution i … When it's a Integer, it's saved, but when it's a Float is it's inserted as a NULL value. So SQL stores the closest value that can be stored in a float. For example, the insertion will fail for the decimal column in the second example. Without the cast, the division would have been made first (as integer division, For example, let's do a simple division as 1234/1233. I change the datatype from float to Decimal(18,2) in SQL, then I update the edmx. But when I do this on SQL Server, we get the following: I need to calculate 3 columns where the mid results are huge decimals, and I'm running into a problem early on with SQL Server basically rounding the decimals regardless of any cast / converts. declare @num as float set @num=5.20 select @num will dispaly only 5.2 But i want it to display as 5.20. as float) but not working... my stdout is showing actually the value being a float : "latitude" : 12.3423 but this is stored as NULL in the database. After a little research i found that it can be solved by using. A calculator will produce 1,00081103000811. When you want to convert from float or real to character data, using the STR string function is usually more useful than CAST( ). AFAICS, the exact 2 decimal places in the display of the value is the presentation layer and therefore it should be handled by your client application, not the SQL Sever (as per my earlier post + Latheesh's last post).. In SQL server float datatype does not display trailing zeros after decimal point. For example, 500 should be 500.00. I have a float datatype and it does not add a decimal point if a number is whole. When I look at the generated code, the column is showing double instead of decimal in C#. This argument is case-insensitive, so either N or n is fine. Any idea? Now when you round it to 5 decimal places, SQL notices that the decimal part is slightly less than 856375, so it rounds DOWN and you get -2702489.85637 as the result. 3 Likes 3,735 Views 1 Comment . The database is NOT a spreadsheet, and, I suspect, you have to think like a database, NOT a spreadsheet when dealing ONLY with the database ( versus moving the data into a spreadsheet ). I also used the CAST(? Now, this is the rule, for database arithmetic. So that is the value that is stored. The way the database back-end ( HSQL database engine ) works, is NOT the same as a spreadsheet. The cast explicitly converts the IntCol1 to float before the division is carried out. Given that, unless you have a compelling reason to change the data type and unless you are able to do sufficient regression testing, I would be reluctant to change the data type. SET FloatCol = CAST(IntCol1 AS float) / IntCol2 WHERE .... SQL Server will switch to non-integer division as soon as one of the operands in of a float or decimal type.
