java - NumberFormat without maximum fraction digits -


is there way create numberformat instance no maximum fraction digits? obvious solution be

numberformat format = numberformat.getnumberinstance(); format.setmaximumfractiondigits(integer.max_value);

but i'm wondering if there's more definitive way of specifying there should no precision limit.

from numberformat api (http://docs.oracle.com/javase/7/docs/api/java/text/numberformat.html):

"setparseintegeronly : affects parsing, e.g. if true, "3456.78" -> 3456 (and leaves parse position after index 6) if false, "3456.78" -> 3456.78 (and leaves parse position after index 8) independent of formatting."

i guess if call setparseintegeronly(false) not worry precision limit, tho i'm kind of stretching facts one.

aha! here go:

numberformat nf = numberformat.getinstance(); nf.setroundingmode(roundingmode.ceiling);

then again, i'm not sure "rounding towards infinity" means. want one:

nf.setroundingmode(roundingmode.unnecessary);
