For example, 500 should be 500.00. 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).. So that is the value that is stored. So SQL stores the closest value that can be stored in a float. This argument is case-insensitive, so either N or n is fine. That closest value is -2702489.85637499997392296791077. This is because STR enables more control over formatting. I have a float datatype and it does not add a decimal point if a number is whole. Decimal Places. In SQL server float datatype does not display trailing zeros after decimal point. 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. select CAST(@num AS numeric(10,2)) But this is not the solution i … HANA SQL: Casting to decimal (implicit or explicit) will not provide rounding. After a little research i found that it can be solved by using. For example, let's do a simple division as 1234/1233. For example, the insertion will fail for the decimal column in the second example. The way the database back-end ( HSQL database engine ) works, is NOT the same as a spreadsheet. When it's a Integer, it's saved, but when it's a Float is it's inserted as a NULL value. 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. Here’s another example, this time using N1 to specify that we only want one decimal place: I change the datatype from float to Decimal(18,2) in SQL, then I update the edmx. Any idea? A calculator will produce 1,00081103000811. Without the cast, the division would have been made first (as integer division, 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. CREATE TABLE #tmp(colA DECIMAL(20,3), colB FLOAT);-- succeeds The cast explicitly converts the IntCol1 to float before the division is carried out. But when I do this on SQL Server, we get the following: I would suggest casting to decimal instead, as float is an imprecise datatype and is prone to "errors" in the result. Now, this is the rule, for database arithmetic. 3 Likes 3,735 Views 1 Comment . I'm working with SQL server and the float values are not able to be saved. 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. Follow RSS feed Like. I also used the CAST(? Converting float and real data. 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. 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 ). declare @num as float set @num=5.20 select @num will dispaly only 5.2 But i want it to display as 5.20. Values of float are truncated when they are converted to any integer type.. When I look at the generated code, the column is showing double instead of decimal in C#. 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. For more information, see STR (Transact-SQL) and Functions (Transact-SQL). When you want to convert from float or real to character data, using the STR string function is usually more useful than CAST( ). 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.
