问题
Hi I want to get numbers from database, for example, if the number in database is 44.7890000000, I would like to get a string 44.789, the same 0.0010000000 -> 0.001, just keep the numbers and trim the tailing '0'. I use this code: qrySth.Fields[i].AsString - it does its job but I find for very small numbers like 0.0000010000 it becomes 1E-6. Is there a way I could disable the scientific notation for this AsString method?
Thanks!

As an alternative to setting the field's DisplayFormat property, you can read from AsFloat and pass the value directly to FormatFloat. It uses the same format pattern.
