Subtracting Variables

2003-04-07 06:45

Hi, Is there a way to subtract Variables? I want to do the following:

 

$F{TOTAL} - ($F(COL1) + $F(COL2))

 

Thanks

Ya, but since they are objects, you'd have to convert them to primitives first. If they were Integers, the code could look like this:

 

new Integer($F{TOTAL).intValue() - ($F{COL1}.intValue() + $F{COL2}.intValue))

Thanks , but the Variables are using class="java.math.BigDecimal"

Then it's even easier. What you want is something like:

 

$F{TOTAL}.subtract($F{COL1}).add($F{COL2})

 

It's all there in the Javadoc for BigDecimal...
