This is almost the same as the formula [field1] / [field2] / field[3] / .. / [fieldn]. Values that are non-numeric or null are ignored. author:    Thomas Morgner Constructor Summary public   ColumnDivisionExpression()      Default constructor. Method Summary public  int getRoundingMode()      Returns the defined rounding mode. public  int getScale()      Returns the scale for the divide-operation. public  Object getValue()      Return the current expression value. public  void setRoundingMode(int roundingMode)      Defines the rounding mode. public  void setScale(int scale)      Defines the scale for the divide-operation. Constructor Detail ColumnDivisionExpression public ColumnDivisionExpression()(Code) Default constructor. Method Detail getRoundingMode public int getRoundingMode()(Code) Returns the defined rounding mode. This influences the precision of the divide-operation. the rounding mode. See Also:   java.math.BigDecimal.divide(java.math.BigDecimalint) getScale public int getScale()(Code) Returns the scale for the divide-operation. The scale influences the precision of the division. the scale. getValue public Object getValue()(Code) Return the current expression value. the value of the function. setRoundingMode public void setRoundingMode(int roundingMode)(Code) Defines the rounding mode. This influences the precision of the divide-operation. Parameters:   roundingMode - the rounding mode. See Also:   java.math.BigDecimal.divide(java.math.BigDecimalint) setScale public void setScale(int scale)(Code) Defines the scale for the divide-operation. The scale influences the precision of the division. Parameters:   scale - the scale.
