Hi Java Team,
I am trying to do calculations for financial reports. I am having problems
avoiding automatic rounding up of my values. I also have problems
avoiding the scientific notation format that is forced on values that
are at least 10e+5.
I haven't had desirable results using the number wrapper classes
to solve these problems. If I need to handle calculations in C, or C++ native
code to achieve these needs, that's fine, but I need to know if
I am incorrectly using Java here, with/without making use of
the Number wrappers
I use the following lines to obtain a product:
double num;
double factor = 2.0;
double bigNumber = 3000000.33;
num = factor * bigNumber;
System.out.println("Factored number is " + String.valueOf(num));
Standard out displays: Factored number is 6e+06
It is necessary that I show 6000000.66 here.
And, if I set bigNumber = 200000.33,
standard shows the factored number is 400001
It is necessary that I show 400000.66 here.
(Using methods from the Double class don't see to help either.)
Perhaps I am not using the String wrapper classes correctly?
.
Thanks in advance for your reply,
-Jill
