----------------------------------
Summary: NumberUtils: Rounding utilities for BigDecimal to
primitive double avoiding NPEs.
Key: LANG-1408
URL: https://issues.apache.org/jira/browse/LANG-1408
Project: Commons Lang
Issue Type: Improvement
Reporter: Rob Tompkins
Assignee: Rob Tompkins
Fix For: 3.8
For the sake of formatting rounded {{BigDecimal}} values in JSON/XML I'm
looking for the following methods:
1.
{code:java}
public static double toDouble(BigDecimal value);
{code}
that defaults to {{0}} when {{value}} is null.
2.
{code:java}
public static double toDouble(BigDecimal value, double defaultValue);
{code}
that essentially does the same as 1. but accommodates for default values being
specified.
3.
{code:java}
public static BigDecimal toScaledBigDecimal(BigDecimal value, Integer scale,
RoundingMode roudingMode);
that converts a {{BigDecimal}} to a {{BigDecimal}} whose scale is the specified
value with input rounding mode applied
{code}
4.
{code:java}
public static BigDecimal toScaledBigDecimal(BigDecimal value);
{code}
that converts a {{BigDecimal}} to a {{BigDecimal}} whose scale is 2 with
{{RoundingMode.HALF_UP}} rounding mode applied.
5.
{code:java}
public static BigDecimal toScaledBigDecimal(Float value, Integer scale,
RoundingMode roudingMode);
{code}
that converts a {{Float}} to a {{BigDecimal}} whose scale is the specified
value with input rounding mode applied.
6.
{code:java}
public static BigDecimal toScaledBigDecimal(Double value, Integer scale,
RoundingMode roudingMode);
{code}
that converts a {{Double}} to a {{BigDecimal}} whose scale is the specified
value with input rounding mode applied.
7.
{code:java}
public static BigDecimal toScaledBigDecimal(Double value);
{code}
that converts a {{Double}} to a {{BigDecimal}} whose scale is 2 with
{{RoundingMode.HALF_UP}} rounding mode applied.
8.
{code:java}
public static BigDecimal toScaledBigDecimal(String value, Integer scale,
RoundingMode roudingMode);
{code}
that converts a {{String}} to a {{BigDecimal}} whose scale is the specified
value with input rounding mode applied
9.
{code:java}
public static BigDecimal toScaledBigDecimal(String value);
{code}
that converts a {{String}} to a {{BigDecimal}} whose scale is 2 with
{{RoundingMode.HALF_UP}} rounding mode applied
