I have a csv file where amount and quantity fields are present in each detail record except header and trailer record. Trailer record has a total charge values which is the total sum of quantity multiplied by amount field in detail records . I need to check whether the trailer total charge value is equal to my calculated value of amoun...
As I retrieve data from a database table an array is populated. Some of the fields are defined as decimal & money fields and within the array they are represented as BigDecimal. I use these array values to populate a CSV file, but the problem is that all BigDecimal values are by default represented in Scientific format (which is the de...

i do the below java print command for this double variable double test=58.15; When i do a System.out.println(test); and System.out.println(new Double(test).toString()); It prints as 58.15. When i do a System.out.println(new BigDecimal(test)) I get the below value 58.14999999999999857891452847979962825775146484375 I am able to unders...
I'm using BigDecimal to represent product prices in a Java SE application. What swing component(s) should I use in order to allow the user to input numbers with only two decimal places and bound it to a BigDecimal variable/Object's property. (Checking that as the user types)? I've been playing with JTextField, JFormattedTextField, Numb...
Is there a guideline for estimating the amount of memory consumed by a BigDecimal? Looking for something similar to these guidelines for estimating String memory usage. ...
Recently I asked which was the best Swing component to bind to a BigDecimal variable (with some particular editing properties). It turns out that none of the standard Swing components suit me completely, nor did the third-party Swing component libraries I've found out there. So I’ve decided to create my own Swing component. Component de...
CentOs 5.4, OpenJDK Runtime Environment (build 1.6.0-b09) MathContext context = new MathContext(2, RoundingMode.FLOOR); BigDecimal total = new BigDecimal("200.0", context); BigDecimal goodPrice = total.divide(BigDecimal.valueOf(3), 2, RoundingMode.FLOOR); System.out.println("divided price=" + goodPrice.toPlainString()); // prints 6...
Is the BigDecimal class broken? It seems like the following should never, ever occur: Note that a.to_f != a.to_s.to_f a.class => BigDecimal a.to_f => 18658.1072928 a.to_s => "10865.81072928" b.class => BigDecimal b.to_f => 10000.0 b.to_s => "10000.0" (...

Hi, I have to convert an incoming String field into a BigDecimal field that would represent a valid amount of money, for example: String amount = "1000"; BigDecimal valid_amount = convert(amount); print(valid_amount.toString())//1000.00 What is the right API to use convert a String into a valid amount of money in Java (eg: apache co...
Is there a mature library for doing decimal-based math, possibly arbitrary-precision, in JavaScript? Edit: I want this information for a reference page on floating-point-related problems and alternatives to use when binary floating-point is inappropriate: http://floating-point-gui.de/ ...
Hello, I've recently migrated a Java 1.4 application to a Java 6 environment. Unfortunately, I encountered a problem with the BigDecimal storage in a Oracle database. To summarize, when I try to store a "7.65E+7" BigDecimal value (76,500,000.00) in the database, Oracle stores in reality the value of 7,650,000.00. This defect is due to t...
I have just completed an evaluation of Java, Groovy and Scala. The factors I considered were: readability, precision The factors I would like to know: performance, ease of integration I needed a BigDecimal level of precision. Here are my results: Java void someOp() { BigDecimal del_theta_1 = toDec(6); BigDecimal del_theta_2...
I have some BigDecimal values which should be indexed for searching. Lucene has NumericField but it has setters only for long, double, float and int. I could store it as a String but then I would not benefit from NumericRangeQuery. How you have stored your BigDecimals? Any best practices to share? ...

Hi guys, I'm importing data from a csv, I need to cast some values to BigDecimal, and raise an error if they can't be parsed.. From testing, BigDecimal("invalid number") returns a BigDecimal of 0. This would be ok, but kind of messy, except a valid value is 0... Float("invalid number") acts differently and throws an exception... My ...
