 net.homecredit.tools.Ft.formatCurrency( new Double( ($F{annuityProc} != null ? $F{annuityProc}.doubleValue() * ($F{creditAmount}.doubleValue()) : ($F{annuityTypeTxt} != null ? $F{annuityTypeTxt}.doubleValue() * ($F{creditAmount}.doubleValue()) : "Данных нет") /100 )) ,"#,##0.00")+" руб."

$F{annuityProc} variable double .
$F{creditAmount} variable double .
$F{annuityTypeTxt} string variable.

You need to multiply $F{annuityProc} by $F{creditAmount} and divide the amount by 100. If $F{annuityProc} null , then you must $F{annuityTypeTxt} multiplied by $F{creditAmount} and the amount divided by 100.
