DecimalFormat df = new DecimalFormat("#.######");
df.format(1.00005522000);

double d = 1.00005522000;
String result = String.format("%.6f", d);

    Do you want to format your double value to 6 decimal points as a String, or do you want a double value that is the result of rounding another double? If you want the latter, then you should use something like `BigDecimal`. A `double` generally cannot represent any specific fractional number exactly. (A number that terminates in base 10 often does not terminate in base 2.) – Ted Hopp Sep 10 '12 at 08:09

string str=1.00005522000;
sting[] newstr=str.split(".");
newstr[0];//contains 1
newstr[1];//contains 00005522000
newstr[1].substring[0,5];//it contains  6 numbers
