Description

For the sake of formatting rounded BigDecimal values in JSON/XML I'm looking for the following methods:

1.

public static double toDouble(BigDecimal value);

that defaults to 0 when value is null.

2.

public static double toDouble(BigDecimal value, double defaultValue);

that essentially does the same as 1. but accommodates for default values being specified.

3.

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

4.

public static BigDecimal toScaledBigDecimal(BigDecimal value);

that converts a BigDecimal to a BigDecimal whose scale is 2 with RoundingMode.HALF_UP rounding mode applied.

5.

public static BigDecimal toScaledBigDecimal(Float value, Integer scale, RoundingMode roudingMode);

that converts a Float to a BigDecimal whose scale is the specified value with input rounding mode applied.

6.

public static BigDecimal toScaledBigDecimal(Double value, Integer scale, RoundingMode roudingMode);

that converts a Double to a BigDecimal whose scale is the specified value with input rounding mode applied.

7.

public static BigDecimal toScaledBigDecimal(Double value);

that converts a Double to a BigDecimal whose scale is 2 with RoundingMode.HALF_UP rounding mode applied.

8.

public static BigDecimal toScaledBigDecimal(String value, Integer scale, RoundingMode roudingMode);

that converts a String to a BigDecimal whose scale is the specified value with input rounding mode applied

9.

public static BigDecimal toScaledBigDecimal(String value);

that converts a String to a BigDecimal whose scale is 2 with RoundingMode.HALF_UP rounding mode applied
