I think the same as emilio , the big decimal is an important thing  to do an ria 
application

I need BigDecimal... +1

I need BigInteger which is part of BigDecimal.

A Google Code project has been started that provides BigDecimal and BigInteger

      http://code.google.com/p/gwt-math/

gwt-math works fine.

Thanks a lot.

Why would you not make these two things part of GWT core?  Seems a bit overkill to
add two more jars just to get BigDecimal and BigInteger support. BigDecimal is pretty
much a must have for any app that deals with numbers that need to be accurate.

+1. Seems odd it has been left out.

Still NotPlanned, but patches are welcome.  We will be happy to consider 
contributions for this.  Please do NOT base any implementation on the 'long' 
primitive.  Longs are emulated in GWT, so such an implementation would be unbearably 
slow with double-emulation.

I'm interested in implementing the BigDecimal and BigInteger support for GWT.

I was thinking of basing the implementation on the OpenJDK or GNU Classpath
implementations. Does Google have preference, maybe based on licensing?

Both of these implementations use int primitives not longs.

Apache licensing would be ideal.

Hey Scott,

Wow quick reply!

Hmm maybe Harmony then?
http://svn.apache.org/viewvc/harmony/enhanced/classlib/trunk/modules/math/src/main/java/java/math/

What do you think the biggest issues will with the GWT implementation? I expect GWT
as implementing integer overflow it will have to be emulated in the BigInteger
implementation.

Overflow is a good one.  Also, efficiency.

Please support this, the existing gwt-math project is lacking at best.

Please support BigDecimal. It's really a fixed price in financial application.

+1.00  kinda shocked this is an open item.

Even if you do not directly support math operations, having the RPC/serialization
layer handle transporting the BigDecimal datatype would at least be something.

It wold be great if BigDecimal support is added to GWT. 
Although I have been using gwt-math. It has some issue, like it does not extend
java.lang.Number. and sum common number functions are missing. Also feels like
BigDecimal should be part of GWT

Wow. Still an issue after almost two years.  I would also benefit from this
enhancement, so if it makes any difference, here's another vote...

gwt-math is stagnant and surely not by far a complete implementation (in fact unless
you're working with strings when initializing BigDecimals there ain't much you can do
with it). ++1

Patches still welcome. :)

Yes, but open source and LGPL should be about letting others do the hard work and you
shamelessly benefiting from their work... :)

I'd like the BigDecimal

Please, get a grip. BigDecimal is needed.

Here is a GWT java.math package implementation I've built:

http://code.google.com/p/gwt-java-math/

It is based on Apache Harmony's implementation but has been modified to run
efficiently in Java Script using doubles rather than longs.

It includes an almost complete implementation of BigInteger, BigDecimal, MathContext,
RoundingMode and Random.

Richard: I read the front of your project page and this sounds pretty sweet.  I could 
see wanting to get this into GWT once it gets some miles on it.  Please keep us posted.

In progress, currently available in the change branch changes/jat/bigdecimal.

Any news?  gwt-math stopped working when we upgraded to GWT 2.0

#43: it still works for me

It was committed to trunk, but then rolled back due some test failures that appeared 
to be related to browser JS differences.  I haven't had a chance to work on it while 
we get 2.0.1 out the door (which is a bug-fix-only release), but it will be in 2.1.

Brilliant.  We've used Hibernate to map Mapics/XA on our iSeries and there are 
BigDeciamls everywhere !!!

Any timescale?  Or "It'll be ready when it's ready"?  :)

Funny you should ask, as I was just working on it while waiting on something else to 
build.  I think it should be ready to re-commit shortly.

Yes jat! Be our big decimal idol!
So GWT becomes an option for displaying and managing financial data. 

Committed to trunk at r7618.
