Re: JUEL rounding issues

That is one solution but it would be nice to fix JUEL. By the way I just had quick look at the calculate method and if you don't set a decimal-scale then 2 is used which seems a bit of a worry as well.

I don't know much about UEL but did run into a rounding issue.

I chose to instead use <calculate> so I could control precision.

Subject: JUEL rounding issues

Out of curiosity today I ran a couple of simple tests using JUEL's
numeric expressions and the results are a bit worrying, here's some
example code:
<set field="value1" value="0.0001" type="BigDecimal"/>
<set field="value2" value="10" type="BigDecimal"/>

<log level="always" message="${resultValue}"></log>

and here are some example results:
0.0001 / 10 = 0
10 / 3 = 3
10.89879 + 6.8978336 = 17.797
10.89879 * 6.8978336 = 75.178
10 - 2.5001 = 7.5

I don't have time right this minute to fix it so just reporting here
so people are aware.  Adrian, I'm not asking you to fix it but if you
have any pointers or suggestions they'd be most welcome.

Regards
Scott
