Subject [jira] [Created] (LANG-843) Providing new class BigDecimalUtils
Date Mon, 08 Oct 2012 08:32:02 GMT
Premysl Maly created LANG-843:

             Summary: Providing new class BigDecimalUtils
                 Key: LANG-843
             Project: Commons Lang
          Issue Type: Improvement
          Components: lang.*
            Reporter: Premysl Maly
            Priority: Minor

Creating Utils class BigDecimalUtils and offering a new implementation of method equals()
in ObjectUtils.

Quoting the javaDoc from BigDecimalUtils:

Provides some extra functionality over the BigDecimal class type Comparing two different BigDecimals
may be tricky, because yet the value is same, the format may differ and then the equals method
implemented on BigDecimal does not return expected results.

   BigDecimal first = new BigDecimal("0.10");
   BigDecimal second = new BigDecimal("0.100");
first.equals(second); will return false, because those two numbers are not using the same
format, even though the values are both "0.1".

  Usage examples:
  Compare a number to 1: if(BigDecimalUtils.equals(someNumber, BigDecimal.ONE))
  compare two numbers whether they are the same value or both null: if(BigDecimalUtils.equals(someNumber,
anotherNumber, NullsEquality.EQUALS))
