RE: [flexcoders] decimal numbers in financial applications

[Gordon Smith]

We're considering adding decimal arithmetic to a future release, but I'm afraid that currently neither the player nor the Flex framework offers this. Decimal arithmetic is not a feature of _javascript_ or ECMAScript, the languages that we've based ActionScript on. So I'm curious how developers writing financial web applications in HTML and _javascript_ solve this problem.   One way to deal with large numbers is to treat them as Strings and do all decimal arithmetic on the server, but that probably isn't practical for you.   Another way might be to use Number to exactly store integral cents rather than fractional dollars. I believe you can store integers up to about 2^52 in a Number.   It sounds like the docs are misleading... where exactly did you read about BigDecimal, so I can have the doc team review what they say?   - Gordon   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of busitech Sent: Wednesday, August 16, 2006 9:06 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] decimal numbers in financial applications   Dear Group, Java BigDecimal serialization to and from the Flash client appears very broken. At best I'd say it's just incomplete. How do those of you who write financial applications with currency or just simple applications which need fixed decimal support deal with this? For example, a number of 1.92 sent to the server in a Number ends up as 1.9199999999999999289457264239899814128875732421875 in the BigDecimal on the other end. If my BigDecimal had a scale of 2 the result is 1.91. I understand that Number is an IEEE-754 double-precision floating-point number, which is the problem here. If Flex is marketed as a piece of business software without good support for dollars and cents, fixed decimal numbers, accurate currency, in short - financial data which drives the business! (Having BigDecimal mentioned in the serialization documentation is so wrong in my mind with this kind of behavior.) Is there something I am missing? Is there a way to make this work correctly? If not, it looks as though I need to port BigDecimal to Actionscript.
