I see what you are doing but i was looking for something more like...

Math.round(variable);
that rounds my variable to the nearest whole number...
i want it only to two decimal places

x = Math.round(x*100.0) / 100.0;

DecimalFormat df2 = new DecimalFormat( "#,###,###,##0.00" );
double dd = 100.2397;
double dd2dec = new Double(df2.format(dd)).doubleValue();

The value of dd2dec will be 100.24

How about: f = (float) (Math.round(n*100.0f)/100.0f);

double r = 5.1234;
System.out.println(r); // r is 5.1234

int decimalPlaces = 2;
BigDecimal bd = new BigDecimal(r);

// setScale is immutable
bd = bd.setScale(decimalPlaces, BigDecimal.ROUND_HALF_UP);
r = bd.doubleValue();

System.out.println(r); // r is 5.12
