SQL Server data modification while importing

In mySql, I have a Float field equals to 4.85

When importing into SQL Server 2008 in a开发者_StackOverflow Float field i get, 4,84999990463257

Someone has an idea why ?

Thanks Jon

Float values are approximations that are accurate to some number of decimal points. Use decimal data type if you want more specific precision.
