Help needed!!!
I use DecimalFormat to round float variables into either two decimals or
zero decimal by using:
DecimalFormat two = new DecimalFormat("0.00");
DecimalFormat zero = new DecimalFormat("0.");
if I have:
float n1 = 1.245, n2 =0;
n1 = Float.parseFloat(zero.format(n1));
n2 = Float.parseFloat(zero.format(n2));
I have two problems here:
1) for the zero decimal format, if the float variable is 0.0, like n2.
sometimes (again not always) the formatted value is 1, not 0 as expected ( I
debugged and found that
zero.format(n2)) return a string of 1. I have tried use
DecimalFormat("#."), without dot as DecimalFormat("#"). They all have the
same results. Anything wrong here?
2) for two decimal format, 1.245 would return 1.24 rather than 1.25. This
is what JAVA API says it's suppose be. I need to round the number to 1.25.
What should I do?
Should I use other method to round the numbers? What that will be?
Thanks for your help.
