How to deal with Number precision in Actionscript?

Question

I have BigDecimal objects serialized with BlazeDS to Actionscript. Once they hit Actionscript as Number objects, they have values like:

140475.32 turns

You may vote and watch the enhancement request in the Flash PLayer Jira bug tracking system at https://bugs.adobe.com/jira/browse/FP-3315

And meanwhile use the Number.toFixed() work-around see : (http://livedocs.adobe.com/flex/3/langref/Number.html#toFixed%28%29)

or use the open source implementations out there : (http://code.google.com/p/bigdecimal/) or (http://www.fxcomps.com/money.html)

As for the serialization efforts, well, it will be small if you use Blazeds or LCDS as they do support Java BigDecimal serialization (to String) cf.

Answer 2

I discovered that BlazeDS supports serializing Java BigDecimal objects to ActionScript Strings as well. So if you don't need the ActionScript data to be Numbers (you are not doing any math on the Flex / ActionScript side) then the String mapping works well (no rounding weirdness). See this link for the BlazeDS mapping options: http://livedocs.adobe.com/blazeds/1/blazeds_devguide/help.html?content=serialize_data_2.html
