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 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
