format - Android DecimalFormat rounding error: Random decimals added -

-

i'm trying format number. can have 2 6 decimal.

if pass number without decimal, results ok. otherwise adds random decimals.

    float value = ...;      decimalformat formatter_currency = new decimalformat();     decimalformatsymbols nf = new decimalformatsymbols();        nf.setdecimalseparator('.');     nf.setgroupingseparator(',');      formatter_currency.setdecimalformatsymbols(nf);     formatter_currency.setmaximumfractiondigits(8);     formatter_currency.setminimumfractiondigits(2);      return formatter_currency.format(value);

eg: value = 35 -> 35.00

value = 35.6 -> 35.65932558 (expected 35.60)

value = 35.659 -> 35.68899918 (expected 35.659)

i've read problem float variable. i've try double, result same.

how can fix this?

thanks

i wrote quick test program , seems pass of test cases:

import java.text.decimalformat; import java.text.decimalformatsymbols;  public class formattest {      public static void main(string[] args) {          double value = 35.659;          decimalformat formatter_currency = new decimalformat();         decimalformatsymbols nf = new decimalformatsymbols();            nf.setdecimalseparator('.');         nf.setgroupingseparator(',');          formatter_currency.setdecimalformatsymbols(nf);         formatter_currency.setmaximumfractiondigits(8);         formatter_currency.setminimumfractiondigits(2);          system.out.println(formatter_currency.format(value));     } }

please try compiling on machine , try putting in different values. tried double instead of float. please let me know if see same results code posted above.
