Math.round in Ireport

[nhutnhut79]

Hello everyone,

SANBEZ had helped  me,  try to use BigDecimal.setScale instead Math.round:  http://community.jaspersoft.com/questions/820117/mathround-two-decimal-ireport-v50.

Result is fine but with data have many record is result fine yet. I think problem at round funtion in Ireprot.  I have an example with 20 record.

 

My job current is convert  formulars from Crystal report to Ireport Jasper. I have many difficulties with Round function because result on report  don't same with old report.

We don't use Pattern property  for this case. I want Math.round(), setScale() return: 20.05 not 20.049999999999997.

 

Please help me!

>> Result is fine but with data have many record is result fine yet

Is it means that all fine? "is fine but... fine yet" : why "but" if all fine?

2.
>> new BigDecimal.setScale(2,ROUND_HULF_UP)
This operation always return 20.05  not 20.0499999999997
Check your report. What are you show in report? Are you sure that it is result of setScale?
