im trying to to print the exact value of R^n, where R is a real number ( 0.0 < R < 99.999 ) and n is an integer such that 0 < n <= 25.
well.. problem is, it just wont let you, so i figured to use BigDecimal, but whenver BigDecimal stores a float number, eg. 1.1 it gives a bunch of useless stuffs at the end
| code: |
BigDecimal num = new BigDecimal(1.1);
System.out.println(num); System.out.println(num.pow(2)); |
see the output, why is that?
and how would you do output the exact value, Formatter? or something else...
Thanks
