Error description
The computation is done differently in CRE vs DE. To avoid confusion in seeing this difference in behavior, we request to have documentation to state this in knowledge center. The computation is done in CRE by the following</span> statement: new</span> java.math.BigDecimal(java.lang.Double. toString(java.lang.Math.exp(<b>value</b></span>.doubleValue()))) ;</span> And in DE by: scoreResponse.cpScore = new</span> java.math. BigDecimal(Math.exp(<b>value</b>.doubleValue()));</span> There is a difference on how doubles are converted to BigDecimal</span> objects. There is no particular reason for this. Converting a double to</span> a String or a BigDecimal is most of the time unpredictable anyway as</span> soon as there is a fractional part. When someone is doing this kind of</span> manipulations (in this case doing conversions to call Math.exp() or</span> other functions that doesn't exist for BigDecimal), he or she should control</span> explicitly the precision and the rounding method. </span>
Local fix
