There are a bunch of approaches, which depend on your java knowledge. For example, expressions:
A)
String.format("%.2f", new BigDecimal(Double.parseDouble($F{sample})))
B)
new DecimalFormat("0.00").format(new Double($F{sample}))
where $F{sample} is a field from dataset, that contains numbers. I used sample query:
SELECT '25.45060506506456' AS sample
Also, attaching report.
