```
public final HostColumnVector.Builder append(BigDecimal value)
```
    Append java.math.BigDecimal into HostColumnVector with UNNECESSARY RoundingMode. Input decimal should have a larger scale than column vector.Otherwise, an ArithmeticException will be thrown while rescaling. If unscaledValue after rescaling exceeds the max precision of rapids type, an ArithmeticException will be thrown while extracting integral.
    
    Parameters:
    
    value - BigDecimal value to be appended
  - append
```
public final HostColumnVector.Builder append(BigDecimal value,
                                             RoundingMode roundingMode)
```
    Append java.math.BigDecimal into HostColumnVector with user-defined RoundingMode. Input decimal will be rescaled according to scale of column type and RoundingMode before appended. If unscaledValue after rescaling exceeds the max precision of rapids type, an ArithmeticException will be thrown.
    
    Parameters:
    
    value - BigDecimal value to be appended
    
    roundingMode - rounding mode determines rescaling behavior
