JDBC Thin Driver - Sqoop is compatible with ojdbc6.jar. This is usually a copy/paste typo. and when stored procedures are used to insert the data. Using Double.longValue When calling an toString() (aDouble.toString()) on Double will never add an extra precisions. valueOf () of String class is a method in Java that simply typecasts below-given parameters to . I find converting to the binary representation easier to grasp this problem. Firstly, a double is not exact. As these methods are for debugging/logging purposes, it shouldn't be the basis of core logic in your code. The double is representing the original float accurately; toString is showing the "extra" data which was already present. How does DNS work when it comes to addresses after slash?

Use the "G17" specifier whose sole purpose is to assure a roundtrip conversion without loss of precision. You are losing precision when you make calculation with double, to make calculation, it better to use BigDecimal, so instead I would go : String str = "21.90"; BigDecimal result = new BigDecimal(str).subtract(BigDecimal.valueOf(21.8)); System.out.println(result); => 0.10 Convert string to double without scientific notation If you use float and double instead of Float and Double use the following: I've encountered this issue today and could not use refactor to BigDecimal, because the project is really huge.

This Approach will not add an extra precisions to your Float value while converting. Some databases provides a direct mode for exports as well. Or is it just there for clarification? This is due the contract of Float.toString(float), which says in part: How many digits must be printed for To use the PostgreSQL Direct Connector, specify the --direct argument for your import or export job. You can see the float is expanded to the double by adding 0s to the end, but that the double representation of 0.27 is 'more accurate', hence the problem. 3.
