I am trying to add -ve to double
List<double> values={12.34,-12}
double value =0.00;
for(double b: values)
{
value += b;
}
I am expecting value of b =0.34 but it returning me 0.399999999985
any idea why it is returning me the wrong value.

3Actually, it gives `0.33999999999999986` – MadProgrammer Jun 30 '14 at 06:40

1Ignoring all the typos in your question and the non-compilable code, that's not wrong. It's just floating-point math. – awksp Jun 30 '14 at 06:41

float[] values={12.34f,-12}; float value =0.00f; for(float b: values) replace 1st three lines with this. then output comes 0.34000 – sayan Jun 30 '14 at 07:06

try this one: double a=12.34; double b=-12; System.out.println(String.format("%.2f" , a+b)); output:0.34 – learner Jun 30 '14 at 07:49
