[jira] [Created] (MATH-622) Default number format does not show
enough digits
Default number format does not show enough digits
-------------------------------------------------
Key: MATH-622
URL: https://issues.apache.org/jira/browse/MATH-622
Project: Commons Math
Issue Type: Improvement
Reporter: Gilles
Priority: Minor
Fix For: 3.0
In {{CompositeFormat}}, the {{getDefaultNumberFormat(final Locale locale)}} method contains
{code}
nf.setMaximumFractionDigits(2);
{code}
This default is too small.
Also, it would be better to output the number in scientific notation.

-----------------------------
Too many tests depend on the default being 2 fractional digits... Reverted in revision 1148385.
Where to go from here?

Gilles commented on MATH-622:
-----------------------------
The "scientific notation" feature is not obvious to achieve because {{CompositeFormat}} uses the {{java.text.NumberFormat}} class. Scientific notation is accessible through the
{{java.text.DecimalFormat}} class but it would not be with the same construct (there is no {{getInstance}} method in {{DecimalFormat}}). One has to use a pattern, thus explicitly create a {{DecimalFormat}} instance.
