Closed as program error.
Error description
Error Message: N/A . Stack Trace: N/A . BigDecimal gives incorrect arithmetic results for the add and subtract operations on the result of a divide.
Local fix
This issue can be worked around by calling the "java.math.BigDecimal.precision()" method on the result of divide operation before the add and subtract operations.
Problem summary
BigDecimal gives incorrect arithmetic results for the add and subtract operations on the result of a divide
Problem conclusion
The BigDecimal code has been adjusted and the issue is fixed via a boolean System property "ibm.java.math.BigDecimal.useSmallerScaleBD". Default value of this property is "false". Set this property value to "true" via command line to apply this fix. . 1) This issue happens with MathContext.DECIMAL32 and MathContext.DECIMAL64. 2) This issue is seen when the return from BigDecimal.divide() is passed as an argument to either BigDecimal.add() or BigDecimal.subtract(). Please check your code for this pattern. . . This APAR will be fixed in the following Java Releases: 8 SR7 FP10 (8.0.7.10) .
