They are not exact!A value stored as FLOAT is translated into nearest binary equivalent. Why 6? Why does that change if I use less trailing zero's? Surely there's a help file entry that explains this behaviour.īeware when using FLOAT. I just don't understand why it truncates (it doesn't round, it truncates) after 6 decimal places. I'd love to use float, but I can't have values changing even if it's seemingly small like after the 6th decimal place. Poor planning on your part does not constitute an emergency on my part. I tried a number of combinations which only resulted in protracted results at the sixth place. 161066Not sure what the answer is, but float seems to work best. That won't do it.should have tested :) Check result of R2 below. Try this CONVERT(DECIMAL(38, 19), / ( - )) AS Result 000 at the end of each integer gives me a result with MORE precision than using 18 zero's after the decimal point?I'VE ALSO TRIEDI've also tried using CAST() around each reference to a field, and around the end result, but all it does is pad the 6 decimal places out with zero's on the end of it.WHY AM I USING THESE DATATYPES?I'm forced to use the DECIMAL(38,19) datatype because some of the values are 19 digits long with no decimal, and others are zero with 19 digits of fractional component, and I can't have the loss of accuracy that comes with using floats.Does anyone know what's going on? Hi Guys, here's one that's doing my head in:SITUATIONI have a table with field names such as, and, each with the datatype decimal(38,19).PROBLEMI have a view in the server management studio that contains: / ( - ) AS Result. We've got lots of great SQL ServerĮxperts to answer whatever question you can come up with. For example, adding an argument null = True to DecimalField will enable it to store empty values for that table in relational database.Site at. We have created an instance of GeeksModel.įield Options are the arguments given to each field for applying some constraint or imparting a particular characteristic to a particular Field.
