If no rounding mode is specified and the exact result cannot be represented, an ArithmeticException is thrown; otherwise, calculations can be carried out to a chosen precision and rounding mode by supplying an appropriate MathContext object to the operation. In either case, eight <em>rounding ...
bigdecimalcannot resolve method 'add' It seems that you are encountering an error where the method 'add' cannot be resolved for BigDecimal. This error typically occurs when you are trying to invoke the 'add' method on a variable that is not of type BigDecimal. To fix this error, ensure ...
otherwise, calculations can be carried out to a chosen precision and rounding mode by supplying an appropriateMathContextobject to the operation. In either case, eight rounding modes are provided for the control of rounding. Using the integer fields in this class (such asROUND_HALF_UP) to repre...
Square brackets are used to represent the particular BigInteger and scale pair defining a BigDecimal value; for example [19, 2] is the BigDecimal numerically equal to 0.19 having a scale of 2. Note: care should be exercised if BigDecimal objects are used as keys in a SortedMap or elements...
