variable expression arithmetic format

2005-11-04 11:40

I have a Double field from my datasource

 

I want to create a Double variable

foo = $F{value} / 10

 

what is the canonical way to do arithemetic in the

"Variable expression" field of the "Add/modify variable"

dialog in iReport?

 

I tried

 

$F{value} / 10

 

and many other combinations of casting and

parenthesis to no avail

 

please help!

 

thanks, dex

new Double($F{value}.doubleValue() / 10)

 

does the trick

 

ah, the joys of java.lang.Number
