How get sum and average BigDecimal values in ireport

Question

I try sum and avg arithmetic operations using ireport for BigDecimal values. Has error anyways when i doing.

-All types are defined BigDecimal in ireport.

-In separete, variables in this example works fine, but i can't doing arithmetic operations with variables.

How sum and average values type BigDecimal?

In my exemple, This is not work:

$F{faturasAuditadasValorTotalLiberado}
.add(new BigDecimal($F{admissaoValorTotalLiberado}, new MathContext(100)))

I try using Java sintax in ireport, but don't work.

I'm use version 3.0.0 ireport. I can't find solution in Jaspersoft community

The default configuration sintax for expression in ireport 3.0.0 is Java

new Long($F{faturasAuditadasQtdDiarias}) + new Long($F{faturasAuditadasQtdDiarias})

I tried, but don't work:

new Long($F{faturasAuditadasQtdDiarias}).sum($F{faturasAuditadasQtdDiarias})


new Long($F{faturasAuditadasQtdDiarias}).sum(new Long($F{faturasAuditadasQtdDiarias}))


$F{faturasAuditadasQtdDiarias}.sum($F{faturasAuditadasQtdDiarias})


$F{faturasAuditadasQtdDiarias} + $F{faturasAuditadasQtdDiarias}

Answer 1

i solved the problem for sum :

 $F{faturasAuditadasValorTotalCobrado} 
.add($F{admissaoValorTotalCobrado}, new MathContext(100)) 
.add($F{altasValorTotalCobrado}, new MathContext(100))
