I think the problem was that I was trying to convert a BigDecimal into a Double. Which is fine if you don't want to subtract.

No, the problem that you make a call to the method

doubleValue() that return a double not a Double object.

 

I think that you have something like this:

 

$F{income}.doubleValue().subtract( $F{expense}.doubleValue() )

 

A right expression is:

 

new Double(

$F{income}.doubleValue(). - $F{expense}.doubleValue() )

The is a dot that is not right in my expression.

 

The right one is this:

 

new Double( $F{income}.doubleValue() - $F{expense}.doubleValue() )
