      use Java dialect and specify MathContext in BigDecimal divide method appropriately.

      e.g.

          $o.setTax($price.subtract($price.divide($taxRate.add(BigDecimal.valueOf(1)), MathContext.DECIMAL128)));

      Or use non-execuble model

    Description

      Executable model generates BigDecimal expressions without using a MathContext as conversely normally done by mvel This implies that an operation like "1/3" is converted into a BigDecimal expression like

      new BigDecimal("1").divide(new BigDecimal("3"))

      causing  this error

      java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result.

          Task - Represents a small unit of work that is not end-user facing. DROOLS-6804 Executable model generates BigDecimal expressions without using a MathContext

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
