Trouble with double primitive type

I have a double value that can get very large, and when it goes over 10 million, java starts storing it in scientific notation.

So if double = 9999999.00, it look to me in the debugger as 9999999.00

But when the double over 10000000.00 it looks like 1.00E7.

It is messing up my report formating. How can I get the number to not convert to scientific notation?

Typically, all double no matter their size are *stored* in scientific notation (okay, actually it's a variation that is given by some IEEE standard). I suspect you are worried more about how the double is *displayed* instead. You should be able to get some control over this by using NumberFormat. Take a look at the API docs (follow the link) for more information.

Anoter option is to turn your double into a BigDecimal. For example
this will print the following:
This is a double :1.0E8
This is a BigDecimal :100000000
